About this product

Model:  zwo_asi2600mc-pro
Part Number:  ASI2600MC-P

Features Sony's highly sensitive 26MP IMX571 APS-C sensor, 2-stage TEC cooling and no Amp Glow! 

The ASI 2600MC Pro uses Sony’s latest back-illuminated IMX571 APS-C format native 16-bit ADC sensor.

Features include ultra-high 14 stops dynamic range, very low 1.0e readout noise and zero amp-glow! 

APS-C format:

The Sony 26 MP APS-C format sensor with 3.76um pixels provides a large well depth of 50ke.

The sensor length and width are 23.5mm x 15.7mm and the diagonal is 28.3mm. 

Beautifully made:

ZWO have worked hard to reduce weight (only 0.7kg) and improve performance. 

All ZWO cameras include a 2-year warranty.

Native 16bit ADC

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

QE Curve

We suppose that the QE peak value of the ASI2600MC Pro is above 80%.

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.

With amp glow – exposure 300 second exposure:

ASI2600 frame with no amp glow – Exposure 300 seconds:


ASI2600MC Pro comes with the polyimide heater that can avoid any dew problems. The heater can be turned off in software if you want to save power.

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 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 0.0024e/s/pix. Which means 300s exposure can only cause 0.7e dark current noise, which is completely negligible!

Took the plunge from DSLR to this. Finally managed to use it last night and I am blown away by the quality. The whole ordering experience was a delight with FLO who gave me guidance as to what was best and cannot recommend this enough

Big sensor, No Amp glow, very High Q.E.
Given it a few minutes on the horsehead with a RASA (before the clouds rolled in)
Gets some nice Subs with short exposure times.
Much Much faster to get Plate-solved and focused than my CCD sensor with the short image transfer times

Nice camera

Chose a bright easy target for first light. Horsehead nebula with L extreme filter. going to have fun with these two items. Thanks guys for the quick delivery in these testing times. But had another fight with DHL in Vietnam. They are useless!
