ASI2600MC Pro
ASI2600MC Pro uses Sony’s latest back-illuminated IMX571 APS-C format sensor with a native 16-bit ADC. It is the color version of the ASI2600MM Pro. It has an impressive range of features that make it a popular choice for astrophotographer. Here are some of the reasons why:
Ultra-low 0e- readout noise – bringing out more details in your images with improved dynamic range
Innovative breakthrough design resulting in zero amp-glow – even during long exposures, which means one thing less to worry about in post-processing
16-bit ADC sensor – giving a high dynamic range of up to 14 stops!
80% peak QE – no need to worry about saturating stars
We have been working hard to reduce the weight of the camera while improving the performance of the camera. After years of technical accumulation and repeated weight loss experiments by ZWO engineers, ZWO finally concentrated the ASI2600 to 0.7KG.
APS-C Format
This is a 26MP camera featuring a small pixel size of 3.76um yet also having the incredible ability of accommodating a large well depth of 50ke.
The sensor length and width are 23.5mm * 15.7mm. The diagonal is 28.3mm.
ASI2600MC Pro
Native 16bit ADC
As one of the few CMOS astronomy cameras with 16-bit ADC on the market, ASI2600 Pro camera was conceived having in mind the optimal characteristics for astrophotography. This 16bit ADC is not a CCD 16bit ADC. It can really achieve a dynamic range output of 14 stop, which will significantly improve the image sharpness and contrast, and also create smoother and more natural contrast transitions (as well as color gradients when using different types of filters).
IMX571 Backlit Sensor
Sony’s back-illuminated CMOS image sensor improves the sensitivity and noise reduction – the key factors to enhancing image quality. It does this by radically realigning the fundamental pixel structure from front-illumination to back-illumination, while still retaining the advantages of CMOS image sensors such as low power consumption and high-speed operation.
With a conventional front-illumination structure, the metal wiring and transistors on the surface of the silicon substrate that form the sensor’s light-sensitive area (photo-diode), impede photon-gathering carried out by the on-chip lens. A back-illuminated structure minimizes the degradation of sensitivity to the optical angle response, while also increasing the amount of light that enters each pixel due to the lack of obstacles such as metal wiring and transistors. These components have been moved to the back-side of the silicon substrate.
Camera Performance
The ASI2600 Pro boasts excellent performance with a dynamic range of up to 14 stops. When the gain value is set to 100, the HCG high gain mode is turned on. We’re not saying it’s magic…but we’d like to think it is pretty close. With the HCG-mode turned on, the readout noise is greatly reduced, and the dynamic range is basically unchanged. To improve the data quality, it is recommended to set the gain to 0 or gain 100 during deep-sky imaging.
Zero Amp Glow
Traditional CMOS sensors produce a weak infrared light source during operation quite often seen in the corner of uncalibrated images. It is the tell-tale signs of ‘amp glow’. As the ASI2600MM Pro uses zero amp glow circuitry, you won’t have to worry about amp glow even when using high gain, long exposure imaging.
Dark frame from ASI2600 without any amp glow – 300s exposure time
Anti-dew
There is a polyimide heater completely fitting the protective window in the ASI2600 Pro camera. It can help avoid any potential annoying dew or icing issues depending on the environment in which you capture images.
The power of the heater is around 5W. You are free to turn it off anytime in your photography software if you want to save power.
QE value
We suppose that the QE peak value of the ASI2600MC Pro is above 80%.
According to the test results of Sony, the QE peak value of the ASI2600MM Pro is 91%.
Two-Stage TEC Cooling, Ultra-Low Dark Current
Thanks to the two stage TEC cooling, ASI2600MM Pro can lower the CMOS sensor temperature to more than 35 degrees Celsius below ambient temperature, which can greatly reduce dark current generation and sensor noise even during extended exposure times.
*The Delta T 35℃ is tested at 30℃ ambient temperature. It might get down when the cooling system is working for a long time. Also, as the ambient temperature falls, the Delta T would also decrease.
The unique dark current suppression technology can further reduce dark current noise. At a cooling temperature of 0 °C, the dark current noise is only 0.0022e/s/pixel. This means a 300s exposure will only cause 0.7e dark current noise, which is less than the readout noise. While at a cooling temperature of -20 °, the dark current can even reduce to 0.00012e/s/pixel, which is completely negligible!
Please notice that the camera needs to be connected to an external 11-14v power supply to implement the cooling function. We recommend you use 12V@3A DC adapter (5.5*2.1mm, center pole positive) or lithium battery with 11-14V to power the camera. If you don’t have one, please click here to buy a 12V power adapter. There are 4 different standard for different countries, please make sure you selected the correct adapter when placing the order.
USB3.0 DDR3 Memory
The ASI2600MM Pro is equipped with a USB 3.0 transmission interface and a built-in DDR3 cache to ensure stable and secure data transmission.
ASI Cooled Cameras produced after August 2023 have changed their DDR3 buffer from 256MB to 512MB.
Please notice that the camera needs to be connected to an external DC 12V @3A~5A power supply adapter for use (connector 5.5*2.1mm, center pole positive). If you don’t have one, clickhereto buy a 12V power adapter. There are 4 different standards for different countries, make sure you selected the correct adapter when placing the order.
Or you can also use lithium battery with 11-14V to power the camera.
Just be aware that power supplies out of this range might cause irreversible damages to your camera.

The Antlia Quad Band Anti-Light Pollution Filter is a light suppression filter for color and monochrome cameras. It is able to shoot most deep sky objects like galaxies, reflection nebulae, emission nebula, and star clusters from a Bortle 8 location to Bortle 1 as its spectral transmission passes through visible light region, near-ultraviolet (NUV) and near-infrared (NIR) region.
Antlia Quad Band filter has a broad bandpass designed to cope with faster optics up to the f/2 focal ratio.
Considering the high quantum efficiency (QE) characteristics of the latest cameras in the near-infrared region and this region is less susceptible to artificial light pollution, the Antlia Quad Band Light-Pollution Filter adds high transmission in the near-infrared (NIR) band. This spectrum design improves image signal-to-noise ratio and contrast by capturing signals in visible bands and NIR region, while also maintaining good color balance and being easier to manage in post-processing.
Certain full-spectrum objects like M51, M83 possess significant signal in the near-infrared (NIR) region, you can possibly capture these deep sky objects more contrasted with the Antlia Quad Band filter under light polluted condition.
When using this filter with a camera that has UV/IR cut protective glass, the visible band transmission signal is retained, but the IR cut limits your ability to capture targets with infrared signal.
Therefore, the Antlia Quad Band filter is more suitable for cameras with AR protective glass as they can capture both NIR and visible band signals.

Antlia SII EDGE narrowband filter optimizes the FWHM (full width half maximum) to 4.5nm bandpass. The suppression of optical density (OD)5 on unwanted wavelengths and the excellent transmittance characteristics found in the Antlia 3nm Pro series has been incorporated into the 4.5nm EDGE narrowband filters. The result is that these filters deliver superior SNR(signal to noise ratio) and better contrast in your images.
Antlia SII 4.5nm EGDE filters are designed to deliver high transmittance at the 671.6nm line that provides you with the maximum signal to reveal the faintest SII nebulae structures.
Conventional broader narrowband filters cause a heavy loss in transmission due to the strong Center Wavelength (CWL)-shift. We guarantee T>90% within 1nm range of the center bandwidth, which means that the SII 4.5nm EDGE narrowband filters can guarantee high transmittance for working with both long focal ratios and fast optical systems. Blue-shift data shows that Antlia 4.5nm EDGE filters can be used with nearly all systems as fast as f/3 with minimal loss in emission signal and meets the requirements of fast optics.
Application and Performance:
High transmittance and narrow bandwidth to maximize contrast
Steep spectral profile minimizes halos around bright stars
A single substrate to eliminate internal reflections

The Askar 103APO is a 103mm aperture, 700mm focal length, and 6.8 native focal ratios OTA. In astrographs, the size of the aperture has a significant impact on observability and image quality. The aperture of 103mm gives it an inherent advantage in terms of light-gathering power, resolution, brightness, and contrast, allowing the photographer to gather more light and present more details and brighter objects in the image. Askar 103APO adopts a triplet air-spaced APO lens design, including one piece of ED glass.
APO(Apochromatic) telescope is a type of telescope with the ability to correct chromatic aberration. Chromatic aberration is a common optical aberration that causes colored edges or blurring around the edges of objects in an image. Other telescopes have relatively simple optical designs and are prone to chromatic aberration, especially at high magnification or in observations where color accuracy is required. However, APO telescopes employ special optical designs and multiple lens elements to correct chromatic aberration, naturally providing higher-quality object details and color accuracy.
In the refractor's element structure, increasing the number of lens elements and designing lens combinations can effectively improve chromatic aberration correction. However, this also means increased production costs and design complexity.
ED glass, also known as low-dispersion glass, is a type of optical glass specifically designed to reduce chromatic aberration. Chromatic aberration occurs because light of different wavelengths refracts differently when passing through a lens, leading to color separation and a decrease in image quality. ED glass has special optical properties that help reduce stray light and effectively minimize chromatic aberration. The Askar 103APO not only adopts a triplet lens design (while budget astrographs on the market typically use doublet), but it also has an ED glass to further enhance image quality.
In addition to the carefully designed lens itself, every aspect of the Askar 103APO is dedicated to providing a better shooting experience for users.
All the inner of the Askar 103APO's dew shield is covered with matting felt, while the inner walls of the main tube are coated with matting paint and equipped with the internal baffle. This effectively reduces light scattering and reflection inside the OTA, thus enhancing the brightness, contrast, and resolution of the observed targets.
Each piece of Askar 103APO is equipped with a unique name ring for identification, making each Askar 103APO telescope exclusive to its owner.
The retractable design of the dew shield, along with the enlarged locking screws, provides convenient usage. The dew shield serves the purpose of protecting the lens from the impact of external and internal light and protecting the lens itself.
On the Askar 103APO, there are a total of two finder bases. Each side of the focuser is equipped with a finder base. Many users have expressed concerns about the limited space for installing additional astronomical accessories along the use. To address this, we have specially set finder bases on both sides of the focuser. This not only eliminates the need for disassembly when changing the position of the finderscope but also provides additional mounting positions for other astronomical accessories. The handle of the Askar 103APO has a special slot design, making it also a base for installing a finder scope. The handle itself is sturdy and durable. The overall design of the tube rings is lightweight, with a total weight of only 750g. The thumb screw of the tube ring allows for easy opening and locking. At the same time, the raised base creates more space to accommodate astronomical accessories. In everyday use, the convenience of each step is taken into consideration.
The dovetail plate is the standard Vixen dovetail plate, compatible with most equatorial mounts and bases on the market. We have also made additional extensions and hole position designs, the length reaching up to 290mm, making it more convenient for balancing on the equatorial mount. With the slot on the handle, the spacing between the tube ring can be adjusted as desired. Additionally, there is also a Losmandy dovetail plate available for purchase, to be used with different equatorial mounts. The detachable main tube design makes it possible for an OTA to down the focal ratio of 4 from the native F6.8. It can also be used for observations with binoviewer.
The Askar 103APO has three optional advanced accessories: a 1x flattener, a 0.8x reducer, and a 0.6x focal reducer. All three accessories have built-in 2" filter threads for direct filter installation. Additionally, they are equipped with M54/M48 adapters, and the 0.6x reducer includes an additional M68 adapter ring for convenient connections.
The 1x flattener does not change the telescope's focal ratio itself. After connecting with the Askar 103APO, it still maintains a focal ratio of 6.8. The flattener corrects field curvature and coma, resulting in flatter field edges and finer star points.The 0.8x reducer can bring the Askar 103APO's focal ratio down to F5.4. This is a standard reducer with field flattening capabilities as well. A shorter focal ratio allows the OTA to have a wider field of view and faster exposure times, making it suitable for capturing large areas of nebulae, star clusters, and faint, fast-moving celestial objects.The 0.6x reducer can bring the Askar 103APO's focal ratio down to F4 while also providing field flattening. Askar 103APO adpots a detachable tube design, where the rear part of the tube can be removed when using the 0.6x reducer, allowing the telescope to have the necessary length to achieve an F4 focal ratio.
Thanks to the detachable lens tube design, the Askar 103APO can be used for observations with binoviewer. In terms of visual observations, the Askar 103APO pays great attention to observation quality. It can easily achieve focus when connected to 1.25" or 2" diagonals or various eyepieces. In terms of the focuser, Askar 103APO is equipped dual-speed rack and pinion large 3.3-inch rigid focuser, which can be compatible with most motorized focusers on the market. There is also a high-precision scale on the 10cm focusing travel. The entire focuser barrel is CNC machined with an anti-reflective internal design and matting paint, providing extra measures to eliminate stray light. The rear of the focuser features a 360° high-precision big rotator, along with precise scales for convenient adjustment and saving of rotation angles, enabling precise rotation. It is also equipped with an enlarged rotator locking screw that can easily secure even under high loads.
The telescope interface at the rear comes with a 1.25"/2" adapter. The entire Askar 103APO tube is crafted using high-quality CNC machining, with anodized and surface spray paint treatment. The orange accents add a bright and eye-catching touch, presenting a stylish and elegant overall appearance. By choosing the Askar 103APO, you will discover that high performance and affordability are not contradictory. Let the Askar 103APO accompany you in exploring the magnificent landscapes of the universe and create unforgettable memories. Take action now and embark on your astronomical adventure with the Askar 103APO!

The 0.6x reducer can bring the Askar 103APO's focal ratio down to F4 while also providing field flattening. Askar 103APO adopts a detachable tube design, where the rear part of the tube can be removed when using the 0.6x reducer, allowing the telescope to have the necessary length to achieve an F4 focal ratio.
The 0.6x reducer adopts a quadruplet design that also supports a 44mm full-frame image circle. The overall weight is 0.98kg. The back focus from the M48 thread is a standard 55mm. The front thread is M84*1. At the camera end, we have equipped three sizes of adapter, M68*1, M54*0.75, and M48*0.75 for easy subsequent connection and use. At the same time, the built-in M48*0.75 2-inch filter thread can be used to install filters directly. The overall CNC machined, both end threaded metal caps prevent ash when not in use.

詳細內容
The SQA55 AF Kit is an astronomical accessory specially designed for the SQA55, which can be used with almost all brands of electronic focusers to realize automatic focusing. By using this kit, users can more easily make focus adjustments to their telescopes, thus improving the precision and efficiency of astronomical observations.
SQA55 AF kit includes many parts:
Three different lengths MXL synchronous belt, one MXL synchronous pulley, one tensioner pulley, three different types Allen wrenches, two M4*10mm screws, one M4*14*5mm screw, one M3*40mm screw, one M4*6mm screw, two M3*10mm screws, two M4*12mm screws.
Attention: The SQA55 and all electronic focusers that appear in the illustrations are not included in this kit and are for display only.
Q: The SQA55 itself can be adapted to electronic focusers, what are the advantages of the SQA55 AF kit?
A:1. Many original adapter plates of electronic focusers are too long, which limits the type of camera or accessory that can be connected to the back of the telescope when in use. However, the SQA55 AF Kit is specially designed with a special length of adapter plate, which allows the SQA55 to be subsequently connected to any accessory required by the user.
2. Most of the original electronic focuser synchronous belts will have an unavoidable backlash, thus affecting the focusing accuracy. The SQA55 AF kit with a tensioner pulley can be used to adjust the synchronous belt to a tight state, which improves the focusing accuracy.
3. Most of the original electronic focuser installation steps are cumbersome. The SQA55 AF kit can be disassembled and assembled as a whole and can be installed in different positions of the SQA55 lens tube to reserve more space for the installation of other required accessories.
4. The SQA55 AF kit is adapted to almost all electronic focusers; if the user chooses a different brand of electronic focuser, it can be easily installed and used.
Q: If I use an electronic focuser with a larger hole distance like the one produced by Pegasus Astro, how do I use the SQA55 AF kit?
A: The L-shaped adapter plate of the SQA55 AF kitt is fully hollow design, just screw down the M4*12 fixing screws, flip theL-shaped adapter plate in the direction, adjust the spacing of the L-shaped adapter plate to a suitable position, and then screw the M4*12 screws on to lock it.

Celestron’s EdgeHD reducers feature a custom 5-element optical design engineered to maintain the flat-field performance of our award-winning EdgeHD optical system. Unlike generic reducers, our premium reducers provide substantial back-focus to accommodate an assortment of imaging accessories.
EdgeHD reducers offer high-index optical elements, including extra-low dispersion, exotic Lanthanum elements, which provide high contrast viewing while minimizing chromatic aberration. All air-to-glass lens surfaces feature multiple layers of coating for maximum light transmission and color correction and contain blacken edges to minimize internal reflection and maximize image contrast. Large diameter lens elements, up to 60mm clear aperture, ensure that the optimized image circle remains at a generous 42mm for use with large CCD sensors.
Incorporating computer assisted CNC machined aluminum housing, for precise spacing and alignment of optical elements, and threaded metal covers on the lens assembly to protect your investment from dust and scratches, our reducers offer you an outstanding mechanical design.
With the Fastar option on all EdgeHD optical systems, coupled with the .7x reducer, your telescope becomes the most complete imaging system available in its price range today.
Performance
Design: 5-element optical layout designed specifically for the EdgeHD 14" to maintain the flat-field performance of the EdgeHD optical design
Maintains the same back focus as when used at f/11: Unlike generic reducers the EdgeHD .7x provides generous back-focus to accommodate additional accessories and a wide variety of cameras. Also allows use of existing EdgeHD T-Adapters and other Celestron imaging accessories
One full F-Stop faster than f/11: Reduces the exposure time by half to capture the same brightness of object
Increase field of view by 43%: Better for capturing wide field images of larger galaxies and nebulae
Glass
Lanthanum Glass Elements: EdgeHD reducer uses "rare earth" Lanthanum glass elements for clear, high contrast viewing while minimizing chromatic aberration
Fully multi-coated lens elements: All air-to-glass surfaces have multiple layers of coating for maximum light transmission and color correction
Blacken edges: All lens elements have blacken edges to minimize internal reflection and maximize contrast
Full Frame Design
Threads directly onto the 3.25" threads of the EdgeHD optical tube: Reduces mechanical vignetting and allows for use with larger (full frame) sensors and Off-Axis Guiders
Clear aperture: 60mm clear aperture lens optimized for a 42mm image circle for use with large CCD sensors.
Mechanical Design
Machined aluminum housing: Computer assisted CNC machined aluminum housing for precise spacing and alignment of the optical elements.
Threaded metal covers for both ends of the lens assembly: To protect your investment from unwanted dust and scratches.
Versatility
Fastar compatibility and f/2 imaging with optional accessory: the EdgeHD is the most complete imaging system in its price range.

Never look directly at the Sun with the naked eye or with an optic (unless you have the proper solar filter). Permanent and irreversible eye damage may result.
Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it.
Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.

Add an internal double-stacking module to the New Lunt 80 mm or Lunt 100 mm Universal Telescopes for a lowered bandpass of <0.5 Angstroms!
The SFPT Double Stack Unit includes a pressure tuner for true Doppler tuning.
Add the SFPT at the time of order, or add it to an existing 80 or 100 mm Lunt Universal Telescope you already own, no trip back to the factory required!
SFPT – Internal Double Stack Module for Lunt 80 mm & 100 mm Universal Day and Night Telescopes
Double stacking provides a truly enhanced, high definition view of the Sun’s surface details. Notably, it lowers the bandpass of the system from <0.7 Angstrom to <0.5 Angstrom, which really makes the surface "pop”!
The Lunt 80 mm and 100mm Universal Telescopes can be internally double-stacked at the time of purchase or anytime thereafter. Furthermore, neither telescope module will need to be returned to the factory for double-stacking.
You can purchase the 80 mm or 100 mm single stack universal telescope initially and add the SFPT to make it a double stack unit later. This will make it more affordable to purchase our a new universal telescope and still have room for upgrades. Once you upgrade your Lunt Universal Telescope with the double stack unit, you will be able to see the finer details not previously visible.

The Lunt LS40FHa Double Stack Unit is intended for use with the Lunt 40mm Dedicated Hydrogen Alpha System and requires a Lunt Solar Systems Blocking Filter (this is a safety requirement).

QHY5III678M/C is a new planetary and guiding camera of the 2nd generation of QHY5III series, the upgraded version of QHY5III178M/C, with excellent near-infrared high sensitivity. The product comes with filters including the IR850 filter.
In this latest generation of sensors, the photodiode portion of the pixel well is physically deeper than in previous sensors, allowing photons of longer wavelengths to penetrate deeper into the substrate. This dramatically increases the sensor’s sensitivity to red and near-infrared (NIR) light. The sensor displays almost equal peak sensitivity to NIR light as it does to light in the visible spectrum.
The QHY5III (Ver. 2) series planetary and guiding cameras are all equipped with a 512MB DDR3 image buffer which can effectively reduce the pressure on computer transmission, a great help for planetary photography which often requires writing a large amount of data in a short period of time. Some deep-sky astrophotography cameras on the market today only have 256MB, for example.
In comparison, the 512MB DDR3 memory of the new 5III (Ver. 2) series cameras represents a significant upgrade.
The custom interfaces of the previous generation of planetary cameras and guiders has been replaced in the QHY5III (Ver.2) cameras with a more universal ST-4 compatible guiding interface. Now, even if the guiding cable is lost or damaged, you will be able to easily get a replacement on the market at a low cost.
The new QHY5III (Ver.2) series of cameras is equipped with a status indicator at the back of the camera. If the camera experiences an abnormal status, the multi-colored indicator light will help to determine the situation with different colors signifying different conditions. During normal operation this indicator light is off, so there is no worry about light contaminating the image.

The QHY5III715C is an ultra-high resolution back-illuminated color camera with extremely low read noise. The sensor has a 1/2.8-inch optical format, 4K resolution with 1.45um pixels. This makes the new QHY5III715C ideal for smaller short focal length refractors. The exceptionally small pixels subtend a FOV of less than 1 arcsecond at focal lengths of 12 inches (300mm) or longer. The QHY5III715C inherits all of the updates and improvements of the QHY5III Series Ver. 2 line of cameras (See below).

In comparison, the 512MB DDR3 memory of the new 5III (Ver. 2) series cameras represents a significant upgrade.
QHY5III (Ver. 2) series cameras have adopted a new front-end design with better compatibility.Here we only take QHY5III200M as example, however, ALL V2 cams in the future share these features.
The BFL of V2 cam is only 8mm, which means you can easily compat a V2 cam with your OAG. The basic top adapter includes 1.25 inch threads and you can still use your 1.25 inch filter.
The top adapter glass of V2 can be easily swiched. One of the adavantage of changable top glasses is you can use one filter even you’re using Lens! You can add a 1.25inch-cs adapter to connect CS lens, or add a second CS-C lens for C-mount lens. The two adapters are all standard accessories of V2 cams. By the way, there’s a 1.25 inch filter wheel adapter to connet your mono planetary cam with QHYCFW3-S filter wheel.
The new QHY5III (Ver.2) series cameras all use the USB3.2 Gen1 Type-C interface. Compared to the USB3.0 Type-B interface used in the previous generation, the Type-C interface has a longer life and is more flexible.
The custom interfaces of the previous generation of planetary cameras and guiders has been replaced in the QHY5III (Ver.2) cameras with a more universal ST-4 compatible guiding interface. Now, even if the guiding cable is lost or damaged, you will be able to easily get a replacement on the market at a low cost.

The PoleMaster is an easy, convenient and fast way to achieve excellent polar alignment. It has been recognized by astronomy enthusiasts around the world and has become a must-have for anyone using an equatorial mount for visual use or for imaging. The PoleMaster electronic polar axis alignment device is a patented product of QHYCCD and is protected by Chinese, US patents and International PCT.
As any seasoned astroimager would agree, achieving good polar alignment is not an easy task. You may spend hours under precious dark sky trying to get that perfect polar alignment, but in the end you may not know whether good alignment has in fact been achieved. Even after you have obtained good alignment, a gentle knock on the mount may send the polar alignment off and you may have no other choice but to start from scratch again. With an hour here and an hour there trying to get polar aligned, it soon will be dawn and time to pack up the geari.
The PoleMaster is a great solution to this problem. The PoleMaster is an innovative product pioneered by QHYCCD to relieve the pain of polar alignment. Using PoleMaster and following a few simple, easy-to-follow, steps you can achieve perfect polar alignment in 2-3 minutes, with an accuracy of up to 30 arc seconds.
With Polemaster, You don’t need to rotate the telescope to some uncomfortable position to keep the optical polar axis of the equatorial mount unobstructed. Also, you don’t need to squat down to look through the polar axis scope. You don’t need to turn off all the light sources to allow the naked eye to adapt to the darkness and look for the Polaris in the field of view. You also don’t need to enter the date and time and then rotate the equatorial mount to a strange angle, finally you don’t need to adjust the equatorial level. With the PoleMaster you can observe the alignment of the polar axis at any time, as well as continuously monitor the polar axis. When the equatorial mount moves inadvertently, you can also tune it back without having to redo everything.
The PoleMaster’s pixel resolution is approximately 30 arc seconds. The camera’s pixel matrix itself is a good ruler, so the accuracy it measures is much higher than the accuracy of the macroscopic lens. In the best case it can achieve an alignment accuracy of 30 arc seconds.
Wide Field of View: The electronic polar mirror has a large field of view of 11 degrees x 8 degrees, so it is easy to find the Polaris.
Once you have calibrated with a PoleMaster, you only need to perform a single-star sync (one-star calibration). This greatly facilitates the setup of an equatorial mount.
With a suitable adapter ring, the PoleMaster can be mounted to any equatorial mount. Even single-axis equatorial mounts that have no ability to correct in declination will benefit because with the PoleMaster, after the polar axis is aligned, the amount of drift in the declination direction will be very small, which can further improve the performance of such an equatorial mount.

詳細內容
- The narrowband UHC filter, like the O-III filter, allows only the two doubly ionized oxygen lines (496 and 501nm) and the hydrogen-beta line (486nm) emissions through while blocking everything else, thus highlighting and revealing the beauty of planetary and emission nebulae. This filter permits superb views of objects like the Orion, Lagoon, Swan and other extended nebulae. It performs well in smaller aperture instruments owing to its greater light transmission than the O-III, yet still suppresses light pollution well. The UHC filter is the best all-around dark-sky nebula filter. Brighter nebulae benefit from increased contrast, and hard-to-see nebulae become visible.
- High-quality filter designed to enhance your views of Emission Nebulae such as the Swan, Lagoon, and the Orion Nebula.
- The UHC filter is the perfect choice for the deep sky observer
- Enhance your views of Emission Nebulae. e.x. the Swan, Lagoon, and the Orion Nebula.
- Screw into 2" telescope focuser/eyepiece.
- Excellent for viewing nebulae under dark sky or the urban sky.

詳細內容
The Starizona Cool Edge was named one of Sky & Telescope's Hot Products for 2012!
This innovative product from Starizona is designed to help rapidly stabilize your telescope with the ambient air temperature.
The Cool Edge is designed with Celestron's new EdgeHD optical system in mind. Because this telescope design has lens elements inside the primary baffle tube, it is not possible to use a traditional SCT cooler that pushes air through the back of the telescope. But the EdgeHD telescopes combine rear-cell air vents with Fastar-compatible optics, allowing the Cool Edge to work from the front of the scope.
The Cool Edge will also work with any Fastar-compatible SCT by simply leaving the scope's visual back open (by removing the diagonal) to allow the air to flow through the optical tube.
The Cool Edge attaches to the telescope just like a HyperStar lens would; you simply remove the secondary mirror and thread the Cool Edge on. All Fastar-compatible telescopes ship with easily removable secondary mirrors to allow the use of a HyperStar lens. This also allows the use of the Cool Edge.
To use, remove the secondary mirror from the telescope, attach the Cool Edge to the front of the telescope, and reattach the secondary mirror to the Cool Edge. The Cool Edge will then move filtered, ambient-temperature air past the secondary mirror, into the telescope, and out through the air vents in the rear cell of an Edge HD or through the open visual back of a non-Edge HD scope.
In just a matter of minutes, the telescope's optics are at ambient temperature. This eliminates distorting tube currents which degrade the image quality.
Features
Rapidly Equalizes Telescope Temperature
Eliminates Tube Currents and Heat Spikes
Fits Celestron Fastar-Compatible Telescopes
Ventilates the Telescope with Filtered Air
Built-in Holder for Secondary Mirror
Anodized Aluminum Construction
Made in USA
Specifications
Size: 4.0" dia. x 4.9" tall
Requires 12v Power (supply included, please choose AC or DC above)

The Starizona RASA 8 Filter Holder allows you to use 2" filters with the Celestron RASA 8" telescope with cameras that are not compatible with a Filter Slider
Starizona's Filter Slider for the Celestron RASA 8" telescope has been one of our most popular products, but only certain ZWO cameras are compatible with the Filter Slider because of the very short backfocus of the RASA 8. Our RASA 8 Filter Holder allows the use of 2" filters with cameras that cannot use the Filter Slider, such as the ZWO ASI2600 and ASI071, plus other brands of cameras including Altair, Atik, QHY, Mallincam and others.
The RASA 8 Filter Holder includes a 5mm M42 spacer to provide a backfocus of 17.5mm, the most common camera backfocus. Other spacers are optionally available for other camera setups. The maximum usable backfocus (without any spacer) is 22.5mm.
To use the RASA 8 Filter Holder, remove the optical window that comes installed in the RASA 8 and install a standard 2" mounted filter in the Filter Holder. The Holder then replaces the standard camera adapter flange from the RASA and is held in place using the stock lock ring. The Filter Holder includes slots so you can still access the collimation screws on the RASA.
What's in the box
T-Spacer (5mm)
Starizona RASA 8 Filter Holder (6.5mm)
* If you have the first version of the RASA 8 Filter Holder your holder will be 5mm tall and came with a 1mm shim for the same total backfocus.

詳細內容
The filter drawers can be pulled in and out using a small knob. This knob is required because the filter slider will be completely flush with your camera, leaving no room to grab the filter drawers. Extra Filter Drawers can be purchased separately.
This Filter System will ONLY work with the following cameras on the RASA 8.
- ZWO ASI1600MM Pro
- ZWO ASI1600MC Pro
- ZWO ASI294MC Pro
- ZWO ASI294MM Pro
- ZWO ASI533MC Pro`
- ZWO ASI533MM Pro
- ZWO ASI183MM Pro
- ZWO ASI183MC Pro
Specifications
- Diameter: 3.10" (78.8mm)
- Thickness: 0.76" (19.5mm)
- Telescope Side Threads: M42 Female Threads
- Camera Side Threads: M42 Female Threads
- Filter Size: Standard 2"
- Weight: 5 oz. (140g)
Using the Filter Slider on the RASA 8
The optical window in the RASA 8 will stay in place. The Filter Slider accounts for the extra optical path length of the filter glass.
Note the Filter Slider can be installed upside down since the threads are the same on both sides, but it will only work in one orientation. The top can be determined by the Starizona logo being right side up. The drawer itself goes all the way up to the top but does not extend all the way down, allowing the drawer to come out without hitting the RASA retaining ring. If the drawer hits this ring, the Slider is probably upside down.
Remove the black 11mm female M42-threaded ring from the front of the ZWO camera. The red male M42 threads on the camera will then go into the female threads on the top of the Filter Slider.

UV IR CUT filter – 1.25″
ZWO 1.25″ IR UV CUT filter is suitable for color camera with AR protect window.
The ZWO IR-Cut Filter blocks infrared light from reaching the sensor of your CCD or CMOS camera or your expensive H-alpha filter. When imaging, the addition of this simple and inexpensive accessory will result in sharper images, and when doing solar work, the IR Cut Filter will your protect H-alpha filter from the damaging effects of infrared radiation.
Infrared or IR light is invisible to the human eye, and so even though most telescopes are not designed to focus IR light, it does not matter when you are using your telescope visually. However, when you add a camera to the mix, its a whole other story! Unlike the human eye, a silicon sensor is very sensitive to light in the infrared portion of the spectrum, and that is a problem because infrared images are blurry as all get out. That means your nice, sharp visual light image is degraded by the addition of the infrared layer. This problem can easily be solved by blocking the infrared, and the ZWO IR Cut-Off, will do just that.
The ZWO IR-Cut filter is housed in a 1.25” cell. The filter comes with a protective plastic case.

The diameter of the camera body is increased to 86mm compared to the ASI071MC Cool (78mm).
▶6 screws seal the chamber
This new structure seals the CMOS chamber better.
▶Anti-dew and cooling system
Thanks to the two-stage TEC cooling, ASI071MC Pro can lower the CMOS sensor temperature to more than 35-40 degrees Celsius below ambient temperature, which can greatly reduce dark current generation and sensor noise even during extended exposure times.
*The Delta T 35-40℃ is tested at 30℃ ambient temperature. It might get down when the cooling system is working for a long time. Also, as the ambient temperature falls, the Delta T would also decrease.
Please notice that the camera needs to be connected to an external 11-14v power supply to implement the cooling function. We recommend you use 12V@3A DC adapter (5.5*2.1mm, center pole positive) or lithium battery with 11-14V to power the camera. If you don’t have one, please click hereto buy a 12V power adapter. There are 4 different standards for different countries, please make sure you selected the correct adapter when placing the order.
The anti-dew heater will heat the AR protect window to avoid any dew problems. The heat anti-dew heater power is around 3.6W and can be turn off in software to save power.

詳細內容
The ASI2400MC Pro is the first CMOS Astro Camera that adopts Sony IMX410 Sensor. Some of the highlights include:
Sony IMX410 full-frame format sensor – giving a great field of view
14-bit ADC – giving high dynamic range
24 MP sensor with a pixel size of 5.94 um – large sensor and large pixels to capture amazing detail
An incredibly large well depth of 100ke- – no need to worry about saturating stars
Ultra-low readout noise of 1.1e- – bringing out more details in your images with improved dynamic range
Zero amp-glow – one thing less to worry about in post-processing.
Considering the above specifications and a peak QE of around 80%, the ASI2400MC Pro is born to be another great innovation of ZWO in the field of full-frame cooled OSC astronomy cameras.
Full Frame OSC Camera
The ASI2400MC Pro uses full-frame format, the sensor length and width are 36mm * 24mm and the diagonal is 43.3mm. Currently it is only available in a one-shoot-colour (OSC) version. OSC is very suitable for those just beginning with astrophotography, but considering the fantastic specifications of this camera, we are sure that many seasoned astrophotographers will take a liking to it as well. If you don’t have the time to take a lot of sub-exposures with different filters, or money to spend on accessories like filters and filter wheels, this camera will deliver amazing images!
IMX410 Backlit Sensor
Sony’s back-illuminated CMOS image sensor improves the sensitivity and noise reduction – the key factors to enhancing image quality. It does this by radically realigning the fundamental pixel structure from front-illumination to back-illumination, while still retaining the advantages of CMOS image sensors such as low power consumption and high-speed operation.
With a conventional front-illumination structure, the metal wiring and transistors on the surface of the silicon substrate that form the sensor’s light-sensitive area (photo-diode), impede photon-gathering carried out by the on-chip lens. A back-illuminated structure minimizes the degradation of sensitivity to the optical angle response, while also increasing the amount of light that enters each pixel due to the lack of obstacles such as metal wiring and transistors. These components have been moved to the back-side of the silicon substrate.
Camera Performance
Large well depth capacity, low read-out noise and high dynamic range.
As an example of the improvements made in the ASI2400MC Pro, a comparison with the full frame ASI-camera ASI128MC shows that the full well capacity of the ASI2400MC Pro is a whopping 132% that of the ASI128MC (even though they have a very similar pixel size of 5.94um vs 5.96um). The ASI2400MC Pro comes with ultra-high a dynamic range of up to 14 stops that will greatly reduce the issue of overexposed images and also help to collect richer color information.
When the gain value is set to 140, the HCG high gain mode is turned on. We’re not saying it’s magic…but we’d like to think it is pretty close. With the HCG-mode turned on, the readout noise is greatly reduced (as low as 1.1e), and the dynamic range is basically unchanged.
Zero Amp Glow
Traditional CMOS sensors produce a weak infrared light source during operation quite often seen in the corner of uncalibrated images as the tell-tale signs of ‘amp glow’. As the ASI2400MC Pro uses zero amp glow circuitry, you won’t have to worry about amp glow even when using high gain, long exposure imaging.
With amp glow – exposure 300 second exposure
ASI2400 frame with no amp glow – Exposure 300 seconds
Anti-Dew
ASI2400MC Pro comes with a polyimide heater that can avoid any dew problems.
The anti-dew heater sits on top of the protective window and will heat it to avoid any dew problems.
The heat anti-dew heater power is around 5W and can be turn off using software in order to save power.
QE Value
We suppose that the QE peak value of the ASI2400MC Pro is above 80%.
Two-Stage TEC Cooling: Ultra-Low Dark Current
Thanks to the two stage TEC cooling, ASI2400MC Pro can lower the CMOS sensor temperature to more than 35 degrees Celsius below ambient temperature, which can greatly reduce dark current generation and sensor noise even during extended exposure times.
*The Delta T 35℃ is tested at 30℃ ambient temperature. It might get down when the cooling system is working for a long time. Also, as the ambient temperature falls, the Delta T would also decrease.
The unique dark current suppression technology can further reduce dark current noise. When it’s cooled to -20℃, the current noise can be as low as 0.00035e/s/pix, which is completely negligible!
Please notice that the camera needs to be connected to an external 11-14v power supply to implement the cooling function. We recommend you use 12V@3A DC adapter (5.5*2.1mm, center pole positive) or lithium battery with 11-14V to power the camera.
USB3.0 & 512M DDR3 Memory
The ASI2400MC Pro is equipped with a USB 3.0 transmission interface and a built-in 256MB (2Gb) DDR3 cache to ensure stable and secure data transmission. During long exposures, it effectively avoids frame dropping and greatly reduces the glow effect caused by slow reading speed.
ASI Cooled Cameras produced after August 2023 have changed their DDR3 buffer from 256MB to 512MB.
Note: This tutorial is for ASI6200, but it also works for ASI2400.

Please notice that the camera needs to be connected to an external DC 12V @3A~5A power supply adapter for use (connector 5.5*2.1mm, center pole positive). If you don’t have one, click here to buy a 12V power adapter. There are 4 different standards for different countries, make sure you selected the correct adapter when placing the order.
Alternatively, you can power the camera using ASIAIR or a lithium battery with 11-14V.
Just be aware that power supplies out of this range might cause irreversible damages to your camera.

Traditional CMOS sensors produce a weak infrared light source during operation quite often seen in the corner of uncalibrated images. It is the tell-tale sign of amp glow. As the ASI2600MC/MM Duo uses zero-amp glow circuitry, you won’t have to worry about amp glow even when using high gain, long exposure imaging.
QE (Quantum efficiency)
Based on our testing results, the QE peak value of ASI2600MC Duo is over 80%, the QE peak value of ASI2600MM Duo is over 91%.
Two-stage TEC cooling
Thanks to the two-stage TEC cooling, ASI2600MC/MM Duo can lower the CMOS sensor temperature to more than 30-35 degrees Celsius below ambient temperature, which can greatly reduce dark current generation and sensor noise even during extended exposure times.
*The Delta T 30-35℃ is tested at 30℃ ambient temperature. It might get down when the cooling system is working for a long time. Also, as the ambient temperature falls, the Delta T would decrease.
Dark current noise
Anti-Dew heater
There is a polyimide heater completely fitting the protective window in the ASI2600MC/MM Duo camera. It can help avoid any potential annoying dew or icing issues depending on the environment in which you capture images.
The power of the heater is around 5W. If you want to save battery, you can always turn it off in your photography software.

ASI2600MM Pro
ASI2600MM Pro uses Sony’s latest back-illuminated IMX571 APS-C format native 16-bit ADC sensor. It’s one of the most anticipated astronomy cameras of 2021. Here is some of the reasons why:
Ultra-high 14 stops dynamic range
Ultra-low 1.0e readout noise
Innovative breakthrough design resulting in zero amp-glow
16-bit ADC sensor
Like the color version, the ASI2600MM Pro also has a very light weight of just 700 grams.
We have been working hard to reduce the weight of the camera while improving the performance of the camera. After years of technical accumulation and repeated weight loss experiments by ZWO engineers, ZWO finally concentrated the ASI2600 to 0.7KG.
APS-C Format
This is a 26MP camera featuring a small pixel size of 3.76um yet also having the incredible ability of accommodating a large well depth of 50ke.
The sensor length and width are 23.5mm * 15.7mm. The diagonal is 28.3mm.
ASI2600MC Pro
Native 16bit ADC
As one of the few CMOS astronomy cameras with 16-bit ADC on the market, ASI2600 Pro camera was conceived having in mind the optimal characteristics for astrophotography. This 16bit ADC is not a CCD 16bit ADC. It can really achieve a dynamic range output of 14 stop, which will significantly improve the image sharpness and contrast, and also create smoother and more natural contrast transitions (as well as color gradients when using different types of filters).
IMX571 Backlit Sensor
Sony’s back-illuminated CMOS image sensor improves the sensitivity and noise reduction – the key factors to enhancing image quality. It does this by radically realigning the fundamental pixel structure from front-illumination to back-illumination, while still retaining the advantages of CMOS image sensors such as low power consumption and high-speed operation.
With a conventional front-illumination structure, the metal wiring and transistors on the surface of the silicon substrate that form the sensor’s light-sensitive area (photo-diode), impede photon-gathering carried out by the on-chip lens. A back-illuminated structure minimizes the degradation of sensitivity to the optical angle response, while also increasing the amount of light that enters each pixel due to the lack of obstacles such as metal wiring and transistors. These components have been moved to the back-side of the silicon substrate.
Camera Performance
The ASI2600 Pro boasts excellent performance with a dynamic range of up to 14 stops. When the gain value is set to 100, the HCG high gain mode is turned on. We’re not saying it’s magic…but we’d like to think it is pretty close. With the HCG-mode turned on, the readout noise is greatly reduced, and the dynamic range is basically unchanged. To improve the data quality, it is recommended to set the gain to 0 or gain 100 during deep-sky imaging.
Zero Amp Glow
Traditional CMOS sensors produce a weak infrared light source during operation quite often seen in the corner of uncalibrated images. It is the tell-tale signs of ‘amp glow’. As the ASI2600MM Pro uses zero amp glow circuitry, you won’t have to worry about amp glow even when using high gain, long exposure imaging.
Dark flame with amp glow – 300s exposure timeDark frame from ASI2600 without any amp glow – 300s exposure time
Anti-dew
There is a polyimide heater completely fitting the protective window in the ASI2600 Pro camera. It can help avoid any potential annoying dew or icing issues depending on the environment in which you capture images.
The power of the heater is around 5W. You are free to turn it off anytime in your photography software if you want to save power.
QE value
We suppose that the QE peak value of the ASI2600MC Pro is above 80%.
According to the test results of Sony, the QE peak value of the ASI2600MM Pro is 91%.
Two-Stage TEC Cooling, Ultra-Low Dark Current
Thanks to the two stage TEC cooling, ASI2600MM Pro can lower the CMOS sensor temperature to more than 35 degrees Celsius below ambient temperature, which can greatly reduce dark current generation and sensor noise even during extended exposure times.
*The Delta T 35℃ is tested at 30℃ ambient temperature. It might get down when the cooling system is working for a long time. Also, as the ambient temperature falls, the Delta T would also decrease.
The unique dark current suppression technology can further reduce dark current noise. At a cooling temperature of 0 °C, the dark current noise is only 0.0022e/s/pixel. This means a 300s exposure will only cause 0.7e dark current noise, which is less than the readout noise. While at a cooling temperature of -20 °, the dark current can even reduce to 0.00012e/s/pixel, which is completely negligible!
Please notice that the camera needs to be connected to an external 11-14v power supply to implement the cooling function. We recommend you use 12V@3A DC adapter (5.5*2.1mm, center pole positive) or lithium battery with 11-14V to power the camera. If you don’t have one, please click here to buy a 12V power adapter. There are 4 different standard for different countries, please make sure you selected the correct adapter when placing the order.
USB3.0 DDR3 Memory
The ASI2600MM Pro is equipped with a USB 3.0 transmission interface and a built-in DDR3 cache to ensure stable and secure data transmission.
ASI Cooled Cameras produced after August 2023 have changed their DDR3 buffer from 256MB to 512MB.
Please notice that the camera needs to be connected to an external DC 12V @3A~5A power supply adapter for use (connector 5.5*2.1mm, center pole positive). If you don’t have one, clickhereto buy a 12V power adapter. There are 4 different standards for different countries, make sure you selected the correct adapter when placing the order.
Or you can also use lithium battery with 11-14V to power the camera.
Just be aware that power supplies out of this range might cause irreversible damages to your camera.

▶IMX294CJK
Sony 10.71M-Effective Pixel Color CMOS Image Sensor (official description from Sony site), with a diagonal of 21.63mm (4/3 format). ZWO has refined the sensor and remolded it to increase the diagonal to 23.2mm with approximately 11.71M-Effective pixels (4/3 format).
▶High-Sensitivity Type 4/3 CMOS Image Sensor that Supports 4K for Astronomic Cameras and Industrial Applications
The IMX294CJK sensor is the first in-house image sensor for astronomic cameras to adopt the 4/3 format and provides the necessary number of pixels for true 4k output at 120 frames per second (w/ ADC 10-bit output mode, the ASI294MC can run up to 25fps at 4k format when used with USB 3.0). In addition, the use of larger-sized pixels achieves SNR1s of 0.14 lx* which is very close to the value of the ASI224 (0.13 lx*).
▶Exceptional low-illumination performance
Exceptional low-illumination performance of SNR1s :0.14lx is realized by use of a large-size optical system and by expanding the area per pixel to 4.63µm. This makes the IMX294CJK ideal for astronomic camera market applications that require low-illumination performance.
14-bit ADC and 13stops dynamic range
ASI294 Pro has very similar parameters as its color version. Both have the 14bit ADC and a high dynamic range of 13 stops, which is even higher than that of the well-known and celebrated ASI1600MM Pro camera.
The ASI294MC Pro has a 14bit ADC unit, allowing it to achieve 13 stops of dynamic range. This is an excellent characteristic for deep sky imaging, which inherently needs high dynamic range. At 13 stops, the ASI294MC has even more dynamic range than the ASI1600.

Camera Performance
Large well depth capacity, low read-out noise and high dynamic range.
The full well capacity of 66387e of ASI294MM Pro is near the top of all ASI DSO cameras. It ensures a very high dynamic range of up to 13 stops that will greatly reduce the issue of overexposed images and also help to collect richer color information.
When the gain value is set to 120, the HCG high gain mode is turned on. We’re not saying it’s magic…but we’d like to think it is pretty close. With the HCG-mode turned on, the readout noise is greatly reduced, and the dynamic range is basically unchanged.
The ASI294MC provides a great full well capacity of 63700e-, which is 3 times higher than the capacity of the highly regarded ASI1600. Even bright stars won’t saturate under long exposures. This also means that this camera can achieve higher SNR (signal to noise ratio) with just one single exposure.
HCG Mode
HCG (high conversion gain) mode, which reduces read noise to even lower levels at higher gain without loss to dynamic range, is automatically enabled when the gain setting is 120 or higher. Read noise will drop under 2e-, while dynamic range will remain at 13 stops.
Unlocked Bin1 Mode
Yet another perk of the ASI294MM Pro is that the pixel size is switchable – you can switch between unlocked Bin1 mode and Bin2 mode anytime in your astrophotography software. The unlocked Bin1 mode changes the pixel size into 2.3um and increases resolution to 8288×5644. The ability to unlock bin1-mode was a popular request from our customers. Of course we listened to you and worked quickly to make it possible.
Remember that using Bin1-mode will decrease the full well capacity compared to the standard bin2-mode.
Unlocked Bin1: 12bit ADC,2.3um pixel size,47megapixels,8288*5644 resolution, 14k full well capacity.
Bin2: 14bit ADC,4.6um pixel size,11.7megapixels,4144*2822 resolution, 66k full well capacity.
You can learn more differences between unlocked Bin1 and Bin2 modes by comparing the performance charts.
If the sampling accuracy you get with the 2.3um pixel size falls within a reasonable range, then the unlocked Bin1 mode will help you get more object details. However, you will lose dynamic range and ADC bit depth. Also the image files you get at Bin1 will probably be around 4 times bigger than Bin2.
So in the end the unlocked Bin1 mode is double-edged, you may choose to use it or not depending on the specific circumstances during your imaging sessions.
Reliable Mechanics
There are four screws on the camera that seal the sensor chamber. This kind of design has been extensively tested and is very stable and secure. Even when used in higher humidity environments, ASI294MM Pro will still work fine without dew problems.

ASI482MC
The ASI482MC is one of the latest OSC planetary cameras released by ZWO in 2021. Packed with Sony sensor IMX482, this camera has some very great highlights, including a large pixel size of 5.8um, compatible with USB 3.0 interface, large full-well depth of 51.5ke-, extremely high sensitivity and super low read out noise, etc. It is considered as one powerful iteration of ZWO after years of developing process in the field of planetary cameras.
1/1.2”format 2 megapixel sensor
The IMX482 sensor adopts back-illuminated CMOS structure. In resolution it is approximately the same as IMX462, but with 4 times the sensor size, it accordingly has a larger pixel size of 5.8*5.8um.
The sensor length and width are 11.13mm*6.26mm. The diagonal is 12.86mm.
SNR1s=0.08lx
Sony is introducing SNR1s [lx] as an index used to quantitatively evaluate picture quality at low illumination. SNR1s [lx] is an acronym consisting of "SNR” (Signal-to-Noise Ratio), "1” (represents that the signal level when noise = 1 is 1), and "s” (for Security). The lower this value is, the greater the image quality will be at low illumination.
The 5.8um large pixel size allows unprecedentedly low SNR1s value of 0.08lx for ASI482MC. While ASI385MC is 0.13lx, you may see it is almost 2 times better, which brings the camera a fantastic nickname – "The King of the Night”.
51.5ke- full well capacity
With the full well capacity of 51.5ke-, ASI482MC displays rich star details when taking astrophotos. Coupled with the ultimately low SNR1s, the efficiency of date acquisition can be really high. This is particularly helpful for solar, lunar and planetary imaging, also makes the camera perfect for DSO lucky imaging (taking multiple photos in short exposure times and stack them to improve SNR.)
Moreover, thanks to the features above, ASI482MC can also be an ideal EAA camera or all-sky camera.
HCG Mode
ASI482MC has a built-in HCG mode which can effectively reduce the readout noise at high gain and keep the same wide dynamic range as you would expect at low gain. When the gain is 80, the HCG mode will automatically turn on. The read out noise fall off a cliff while the dynamic range still can reach close to 12 stops. The minimum read noise is 1.5 e.
QE curve
We assume the QE peak value of ASI482MC is 85% at 530nm.
USB 3.0 Port & ST4 Port
USB 3.0 Port: Like other ASI cameras, the ASI482MC is powered and controlled via USB 3.0. It provides 5Gb bandwidth to let the camera run at 82.5fps (10bit, high speed mode) or 57.5fps (12bit, normal mode) at full resolution (2Mega).
ST4 Port: Can be used to connect with auto guide port of mount for guiding.

詳細內容
ASI585MC Pro is a new ZWO deep sky camera based on the 4k SONY CMOS sensor with a 1/1.2″ format and 2.9μm pixels. It has a super high sensitivity and a large resolution of 3840*2160 (8.29MP in total). It also features high transmission speeds – In high-speed mode, the fast frame rate can reach 47fps at full resolution! Being an entry-level DSO camera, it offers great advantages of high cost-effectiveness.
Note:
External power supplies are needed for all ASl-cooled cameras. We recommend you use a 12V@3A~5A DC adapter (D5.5×2.1mm, center pole positive) or a lithium battery with 11-14V to power the camera. You can also use ASIAlR to power the cameras. Be aware that using a power supply out of this voltage range will probably lead to irreparable damage to the camera.
ASI585MC Pro
One Camera for All
The STARVIS 2 technology brings ASI585MC Pro more advanced imaging performance compared to other cooled cameras. Its high frame rate makes it not only suitable for DSO photography but also solar/lunar/planetary photography.
Jupiter -Jim RiveraMoon -Christopher Schementi
NGC3372 -Simon LewisM42 -Simon Lewis
STARVIS 2
STARVIS 2 was developed by SONY and evolved from STARVIS. It is the latest technology with a wider dynamic range and super-high sensitivity beyond the human eye. Benefiting from it, ASI585MC Pro’s sensitivity and signal-to-noise ratio is greatly improved.
Large Full Well Capacity
The back-illuminated structure improves the camera’s full well capacity. Even with unbinned 2.9μm pixels, ASI585MC Pro has a full well capacity of 40ke-, nearly 3 times that of the last-generation sensor IMX485. A larger full well capacity gets the camera higher efficiency in collecting light, can effectively restrain the highlight area from being overexposed, and also can improve the signal-to-noise ratio.
Zero Amp Glow
ASI585MC Pro exhibits extremely clean dark frames with zero amp glow! No matter how long the exposure and how high the gain value is, you can easily get clean and smooth astro images!
Note: This feature is implemented directly at the hardware level, it does not require software control.
512MB DDR3
ASI585MC Pro uses a USB 3.0 interface, along with the built-in 512MB DDR3 cache, ensuring high-speed, smooth, and stable data transmission.
USB 3.0 Port & USB 2.0 HUB
USB 3.0 Port: Provides 5Gb bandwidth to allow ASI585MC Pro to run at 47fps at 8.29MP full resolution (10bit, high-speed mode).
USB 2.0 HUB: Can be used to connect various kinds of USB devices such as EFW, guide camera, and EAF.
Two-stage TEC Cooling
Thanks to the two-stage TEC cooling, ASI585MC Pro can lower the CMOS sensor temperature to more than 35 degrees Celsius below ambient temperature, which can greatly reduce dark current generation and sensor noise even during extended exposure times.
*The Delta T 35℃ is tested at 30℃ ambient temperature. It might get down when the cooling system is working for a long time. Also, as the ambient temperature falls, the Delta T would decrease.
Below is the dark current curve of ASI585MC Pro at the temperature from -20℃ to 30℃.
Camera Performance
Low read noise, High dynamic range
The camera has a built-in HCG mode, which can effectively reduce read noise at high gain and allow the camera to maintain the same high dynamic range as it does at low gain.
When the gain reaches 252, the HCG mode will be automatically turned on and the dynamic range reaches a level close to 11bit. The read noise in this case can be as low as 0.7e.
QE (Quantum efficiency)
Based on our testing results, the QE peak value of ASI585MC Pro is 91%.

ASI6200MC Pro
All Pro cameras (with cooler) need to be connected to an external 11-14v power supply to image. You can also use ASIAIR to power the cameras.
Even when the cooler is not being used the power supply must be used for the camera to be recognized.
ASI6200MC Pro uses Sony’s latest back-illuminated IMX455 Full Frame format native 16-bit ADC sensor. It has3.76µm, ultra-low 1.2e readout noise and an innovative breakthrough resulting in zero amp-glow.
The new ASI6200MC Pro camera is the color version of the ASI6200MM Pro. It combines an optimal set of characteristics for you to be able to take amazing images. Its huge sensor and full-frame format will let you capture detailed, large images. If you feel that a one-shot-camera is preferred over a monochrome camera (which requires dedicated equipment and exposures using different filters), then this camera is for you. Some of the highlights include:
Sony IMX455 full-frame format sensor – giving a great field of view
True 16-bit ADC – giving a high dynamic range of up to 14 stops!
62-megapixel sensor with a pixel size of 3.76um – huge sensor and relatively small pixel size to capture amazing detail across a large field-of-view
A large well depth of4ke- – no need to worry about saturating stars
Ultra-low readout noise of 1.2 e- – bringing out more details in your images with improved dynamic range
Zero amp-glow – even during long exposures, which means one thing less to worry about in post-processing
We have been working hard to reduce the weight of the camera while still improving the overall performance. After years of technical accumulation and repeated mass-reduction experiments by ZWO engineers, ZWO finally got the weight of the ASI6200 down to just 700 grams.
Full Frame format
The ASI6200 Pro camera uses a full-frame format. The sensor length and width are 36mm * 24mm respectively, and the diagonal is 43.3mm. This is a 62MP camera with a small pixel size of 3.76um that can accommodate a large well depth of 51.4ke.
Native 16bit ADC
ASI6200 Pro camera is our first batch of CMOS astronomy cameras with true 16-bit ADC. It is not a CCD-style 16-bit ADC – it really can achieve a dynamic range output of 14 stops. This significantly improves the image sharpness and contrast, and the contrast gradients are smoother and more natural-looking.
IMX455 backlit sensor
Sony’s back-illuminated CMOS image sensor improves the sensitivity and noise reduction – the key factors to enhancing image quality. It does this by radically realigning the fundamental pixel structure from front-illumination to back-illumination, while still retaining the advantages of CMOS image sensors such as low power consumption and high-speed operation.
With a conventional front-illumination structure, the metal wiring and transistors on the surface of the silicon substrate that form the sensor’s light-sensitive area (photo-diode), impede photon-gathering carried out by the on-chip lens. A back-illuminated structure minimizes the degradation of sensitivity to the optical angle response, while also increasing the amount of light that enters each pixel due to the lack of obstacles such as metal wiring and transistors. These components have been moved to the back-side of the silicon substrate.
CameraPerformance
The ASI6200 Pro camera has excellent performance with a dynamic range of up to 14 stops that will greatly reduce the issue of overexposed images, and make colour gradients look smoother and more natural-looking.
When the gain value is set to 100, the HCG high gain mode is turned on. We’re not saying it’s magic…but we’d like to think it is pretty close. With the HCG-mode turned on, the readout noise is greatly reduced, and the dynamic range is basically unchanged.
Zero Amp Glow
Traditional CMOS sensors produce a weak infrared light source during operation quite often seen in the corner of uncalibrated images as the tell-tale signs of ‘amp glow’. As the ASI6200 camera uses zero amp glow circuitry, you won’t have to worry about amp glow even when using high gain, long exposure imaging.
With amp glow – exposure 300 second exposureASI6200 frame with no amp glow – Exposure 300 seconds
Anti-dew
ASI6200MC Pro comes with the polyimide heater that can avoid any dew problems.
The anti-dew heater which completely fit the protective window will heat it to avoid any dew problems.
The heat anti-dew heater power is around 5W and can be turn off in software to save power.
QE value
The QE peak value of the ASI6200 Pro camera is 91%.
Two-stage TEC cooling, ultra-low dark current
Thanks to the two stage TEC cooling, ASI6200MC Pro can lower the CMOS sensor temperature to more than 35 degrees Celsius below ambient temperature, which can greatly reduce dark current generation and sensor noise even during extended exposure times.
*The Delta T 35℃ is tested at 30℃ ambient temperature. It might get down when the cooling system is working for a long time. Also, as the ambient temperature falls, the Delta T would also decrease.
The unique dark current suppression technology can further reduce dark current noise. At a cooling temperature of 0 °C, the dark current noise is only 0.003e/s/pixel. This means a 300s exposure will only cause a dark current noise of 0.9e-, which is completely negligible!
Please notice that the camera needs to be connected to an external 11-14v power supply to implement the cooling function. We recommend you use 12V@3A DC adapter (5.5*2.1mm, center pole positive) or lithium battery with 11-14V to power the camera. If you don’t have one, please click hereto buy a 12V power adapter. There are 4 different standard for different countries, please make sure you selected the correct adapter when placing the order.
USB3.0 & 256M DDR3 Memory
The ASI6200 Pro camera is equipped with a USB 3.0 transmission interface and a built-in 256MB DDR3 cache to ensure stable and secure data transmission.
ASI Cooled Cameras produced after August 2023 have changed their DDR3 buffer from 256MB to 512MB.

Product Description
The M54 tilter is making sensor tilt adjustment much easier than before by allowing you to do the adjustment on the rear end of the camera. You now can make some adjustments during imaging, instead of taking the camera off from the telescope.
* Notice: Before you purchase the M54 tilter, it is better to consult our customer service to confirm whether it fits your setup.
How to install the M54 tilter?
Use a hex wrench to take off the three M3 cylindrical screws on the adapter.
Disassemble the sensor tilt plate from the DSO camera.
Place the base of the M54-Tilter onto the cooled camera. Fix them with six 5*6Phillips flat-head screws.
Then place the top cover of the M54 tilter onto the camera. Turn over them and fix the base and top cover with three M3 screws. Please do align the screws to the M3 screw holes (as shown in the mechanical drawing below). The angle between each two M3 screws should be 120°.
