  • An APS-C camera built with astrophotography in mind.
  • Cooling system reaching up to -35 degrees Celsius below ambient temperature. 
  • Stay efficient in your imaging sessions with a quantum efficiency reaching up to 80%!
  • Pixel Size: 3.76 microns.

Product Details

  • The ZWO ASI2600 Pro USB3.0 Cooled Color CMOS Camera is perfect for the avid astrophotographer wanting a high-grade camera with an APS-C style sensor. The Sony IMX571 sensor used in this camera is back-illuminated, allowing better light acquisition than front-illuminated sensors of the same style. This is because back-illumination by design has fewer obstructions to the sensor which provides a more efficient imaging experience overall.

    Complete with extremely effective cooling technologies and USB 3.0 connection, this camera is a powerhouse to work with. The Resolution is 6248 x 4176 pixels at 3.76-micron pixel size and a Quantum Efficiency reaching over 80%! 

    The max frames per second at full resolution are 3.51/fps and has an exposure range of 32 microns to the 2000s, which means you have a great variety in what you will be able to image.

    Features of the ZWO ASI2600 Camera

    ASI2600MC Pro uses Sony’s latest back-illuminated IMX571 APS-C format native 16-bit ADC sensor. It has an ultra-high 14 stops dynamic range, ultra-low 1.0e readout noise and an innovative breakthrough resulting in zero amp-glow. It is a camera born from the appeal of astrophotography lovers.

    Amazing Craftsmanship, Lightweight body, Solid image quality:

    ZWO 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:

    The ASI2600MC Pro uses APS-C format, the sensor length and width are 23.5 mm x 15.7 mm and the diagonal is 28.3 mm. This is a 26MP camera with a small pixel size of 3.76 microns that can accommodate a large well depth of 50 ke.

    Anti-dew

    ASI2600MC Pro comes with the polyimide heater. The anti-dew heater which completely fits 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.

    Native 16bit ADC:

    ASI2600MC Pro is our first batch of CMOS astronomy cameras with 16-bit ADC. This 16-bit ADC is not a CCD 16-bit ADC, and it can really achieve a dynamic range output of 14 stops. This significantly improves the image sharpness and contrast, and the color changes are smoother and more natural.

    IMX571 backlit sensor:

    Sony’s back-illuminated CMOS image sensor improves sensitivity and noise reduction – the key factors to enhancing image quality, while radically realigning their fundamental pixel structure from front-illumination to back-illumination. It has retained 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 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 that have been moved to the reverse of the silicon substrate.

    Sony has developed a unique photo-diode structure and on-chip lens optimized for back-illuminated structures, that achieve higher sensitivity and a lower random noise without light by reducing noise, dark current, and defect pixels compared to the conventional front-illuminated structure.

    Camera Performance

    The ASI2600MC Pro has excellent performance with a dynamic range of up to 14stops. When the gain value is 100, the magical HCG high gain mode is turned on, the readout noise is greatly reduced, and the dynamic range is basically unchanged. It is recommended to set the gain to 0 or gain 100 in deep space.

    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 ASI2600MC Pro uses zero amp glow circuitry, you won’t have to worry about amp glow even when using high gain, long exposure imaging.

    Two-stage TEC cooling, ultra-low dark current:

    Like the ASI6200, the ASI2600MC Pro also uses two stage TEC cooling and can lower the CMOS sensor temperature to more that 35-degrees C below ambient, which can greatly reduce dark current generation and sensor noise even with extended exposure times.

    The unique dark current suppression technology can even further reduce dark current noise.

    At a cooling temperature of 0 °C, the dark current noise is only 0.003e/s/pix. Which means 300s exposure can only cause 0.9e dark current noise, which is less than the readout noise. While at a cooling temperature of -20 °C, the dark current can even reduce to 0.00021e/s/pix, which is completely negligible!

    DDR3 Memory Buffer

    The ASI2600MC Pro is equipped with a USB 3.0 transmission interface and a built-in 256MB DDR3 cache to ensure stable and secure data transmission. Under long exposure, it effectively avoids frame dropping and greatly reduces the glow effect caused by slow reading speed.

Works Wonderfully with INDI on Linux

Stepping up from the ASI1600MC-Pro to the 16-bit APS-C sized ASI2600MC-Pro, I was worried that it may not be as big of a step up as the price is, but I was wrong. Having a true 16-bit sensor makes all the difference in subtle gradients when imaging. I've only been able to image with it twice, but M13 shows incredible variations of star colors, and the Iris Nebula shows nice blues, as well as all of the dark dust surrounding it. The camera works great with INDI and KStars on Linux.

Unreal

After Mack Murdock gave me some outstanding advice I made the decision to pick up the 2600MC Pro. It is nothing short of perfection. The signal to nose ratio is off the charts. I don’t even bother with dark frames anymore. And frankly, I don’t bother with calibration of any kind. This camera is easy to use and pairs amazingly well with the ASI Air Pro. Do it. Buy one.

Great step up from DSLR

This is my first dedicated astro-camera after using a modified DSLR for years. I really like the low noise darks and bias this camera provides. Interfacing via ASCOM works well -- no drop outs or software crashes. Image quality is excellent at my imaging scale of 0.9 arcsec / pixel

Big improvement over the ASI294

Low noise, great resolution. No problems with dew or cooling. . .no problems at all. The weight is not an issue; it hangs off the end of my rather long and lightweight TeleVue ns101np without any problem. Cooling runs fun though it’s not a big challenge here in SoCal. Darks, flats and flat darks cleaned up the image without any artifacts. That was the problem with the ASI294: using a light pollution filter brought out all sorts of weird things in the background. No so with this camera, not even with the Triad Ultra.
