All Pro cameras (with cooler) need to be connected to an external 11-15v power supply to image.
Even when the cooler is not being used the power supply must be used for the camera to be recognized.
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 colour version, the ASI2600MM Pro also has a very light weight of just 700 grams.
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.
Native 16bit ADC:
As one of the few CMOS astronomy cameras with 16-bit ADC on the market, ASI2600MM Pro 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 colour 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.
The ASI2600MM 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 time
Dark frame from ASI2600 without any amp glow – 300s exposure time
There is a polyimide heater completely fitting the protective window in the ASI2600MM 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.
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 11-15v 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 11-15V to power the camera. If you don’t have one, please click here to 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.
USB3.0 & 256M DDR3 Memory:
The ASI2600MM Pro is equipped with a USB 3.0 transmission interface and a built-in 256MB DDR3 cache to ensure stable and secure data transmission.

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.
Or you can also use lithium battery with 11-15V to power the camera.
Just be aware that power supplies out of this range might cause irreversible damages to your camera.

Anthony Uy – :
Hello! I encountered a problem with this camera (2600MM-pro). I noticed severe elongated stars due to vibrations of the cooling fan. I tried another camera (2600MC-pro) that I have and it does not have the problem. I just realized it was from the cooling fan, because when I turned off the fan, the stars of the 2600MM-pro became perfectly round. Is there a solution to this?
Memory Ji – :
Please try to Adjust the 4 screws that fix the fan counterclockwise, keep the 4 feet of the fan on the same level.
Russ – :
This is a 2-star rating on the 2600MM and 2600MC line of cameras due to the oil on the sensor. I find it hard to believe that ZWO finds it acceptable for users to periodically open up the chamber on this $2000 camera and run the risk of permanently damaging the sensor surface. Any other company with a product this expensive would void your warranty if you cracked it open. ZWO is directing its customers to open this camera to remedy a design flaw.
sara.liu – :
Truly sorry for the inconvenience.
The warranty is not affected if the camera is cleaned and opened due to oil leakage.
Veaceslav – :
I have notice some oil on sensor. How to remove it correctly?
sara.liu – :
I think this article will be helpful to you.
David (verified owner) – :
If I want to cool the camera I would have to connect a power cord directly to my power supply or take the cable to the asiairpro and from there to the power supply?
sara.liu – :
It is possible to take the cable to the asiairpro and from there to the power the ASI cameras.
Sonnvik – :
Do you have an option to fit this camera to an EOS lens together with a filter wheel? Ideally I would like to have an OAG as well but I guess that will be hard to do?
sara.liu – :
OAG is hard. The EFW2-EOS can connect 2600 to an EOS lens together with a filter wheel. Here is the link for your reference:https://astronomy-imaging-camera.com/product/eos-lens-adapter-for-2-filter-wheel
John Ott – :
Are the 2600 MM Pro (mono) and 294 MM Pro (mono ) USB 3.0 interfaces compatible with the latest USB 3.1 protocol? I don’t expect it to run at 3.1 transfer rates just need to know if there is any incompatibilities between USB 3.1 and 3.0.
sara.liu – :
The USB 3.1 is compatible with the USB 3.0, the transfer rates would depend on USB 3.0.
Bousquet – :
When will this camera be available, and do you have a GT version planned?
Support@ZWO – :
Please contact email@example.com about the available time.
There is no GT version plan for this camera.
