Native 16bit ADC

As one of the few CMOS astronomy cameras with 16bit ADC in the market, ASI2600MM Pro is perfect 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, also create smoother and more natural colour transitions.

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

DDR Memory Buffer

ZWO Pro cameras feature a 256MB DDR3 memory buffer to enable data transfer stability and reduced amp-glow caused by the slow data transfer speed when using a USB2.0 port.

Camera Performance

The ASI2600MM 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. For better date quality, it is recommended to set the gain to 0 or gain 100 during deep-sky imaging.

QE Curve

According to the test results of Sony, the QE peak value of the ASI2600MM Pro is 91%.

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 ASI2600MM Pro uses zero amp glow circuitry, you won’t have to worry about amp glow even when using high gain, long exposure imaging.

Anti-dew

There is a polyimide heater completely fitting the protective window in the ASI2600MM Pro camera. It can help avoid the annoying dew or icing issues.

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 some power.

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 that 35c 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 °, the dark current noise is only 0.0022e/s/pix. Which means 300s exposure can 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/pix, which is completely negligible!

I bought this to replace/supplement an eight year old SX-694. So far I have found the ASI2600 easy to use and giving very good results, on both an MN190 and a WO81, using the INDI drivers and Ekos. Any vignetting has been taken out well by flats. I have largely been using NB filters, and the performance is good with these. I use a USB2 port, rather than USB3, so cannot comment on the performance with the latter although download speeds on USB2 seem similar to the SX694 despite the larger file sizes on the ASI2600. My only issue has been some USB connectivity problems using the camera as a USB hub for a filter wheel, but I have yet to really troublershoot these. Overall, I am very satisfied with the camera.

ZWO ASI 2600MM-Pro Camera
Monday, 15 February 2021  | 

I have only had this camera for a week and have used it over three nights of imaging. It is bolted directly to the face of a ZWO 2" filter wheel.
While taking dark frames, light leakage is apparent into the system which may be from the camera/filter wheel interface.
So long as dark frames are taken in a dark environment this does not present a problem and actual sub frames are not affected when imaging at night.
The screw fitting on this camera is M42 female rather than M42 male on the ASI533. There is no simple adapter that allows for a screw fit of the camera to the 2" EFW (M54 female) which may eliminate the light leakage issue.
The noise performance is excellent - perhaps even better than my ASI 533 camera. There are very few hot pixels visible.
I was worried about back focus and sensor tilt, but keeping the spacing distance identical to the ASI533 camera, back focus was spot on and I have no elliptical stars in the images taken to date.
This is just as well as the 'bolt on' method of fitting the camera to the EFW makes it impossible to access the tilt adjustment screws without dismantling the filter wheel to remove the camera.
This would be an extremely lengthy iterative process, taking may hours to get set up correct and risks introducing allot of dust into the optics.
The only way to relocate the tilt adjustment after the EFW is to filt ZWOs OAG unit which I don't have or need to use.
Using this camera has more than doubled the field of view that I can achieve with my eSPRIT100ED refractor allowing larger DSOs to be imaged without requiring a mosaic.
I am excited in getting into narrow band imaging, I do not have sufficient experience to compare with other mono camera options.
