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.
 
 
 
ASI2600MM Pro uses Sony’s latest back-illuminated IMX571 APS-C format native 16-bit ADC sensor. With the ultra-high 14 stops dynamic range, ultra-low 1.0e readout noise and an innovative breakthrough resulting in zero amp-glow, it’s become one of the best astrophotography cameras available today.
 
APS-C Sensor
The ZWO ASI2600MM Pro is a 26-megapixel 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 x 15.7mm with a diagonal is 28.3mm. Like its color equivalent, the ASI2600MC Pro, ASI2600MM Pro also has a very light weight of 0.7KG.
Native 16bit ADC
As one of the few CMOS astronomy cameras with 16bit ADC in the market, ASI2600MM Pro was born with superiorities for astrophotography. This 16bit ADC is not a CCD 16bit ADC. It can truly achieve a dynamic range output of 14 stops, which will significantly improve the image sharpness and contrast, also create smoother and more natural color transitions.
MX571 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.
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.
