The ZWO ASI2600MM PRO uses the back-illuminated Sony ExMor IMX571 APS-C sensor. It features a QE up to 80%, a native bit rate of 16 bits, an ultra-high 14 stops dynamic range and ultra-low 1.0e readout noise.

Like the colour version, this camera weighs only 700 grams! The APS-C sensor has the size of 23.5mm x 15.7mm for a diagonal of 28.3mm.

Sony’s back-illuminated CMOS technology improves sensitivity, minimizes noise, reduces power consumption and increases data download speed. In a conventional front-illumination structure, the interconnection of metal wiring and transistors are above the photosensitive silicon surface (photo diode), reducing the overall sensitivity and therefore the quantum efficiency. In back-illuminated sensors, the photosensitive surface is placed on top of the wiring so the incoming light is not obstructed, resulting in a greater quantum efficiency. Sony has developed a new and unique photo-diode structure and an on-chip lens that is optimized for back-illuminated structures, achieving a higher sensitivity and a lower random noise.

The ASI2600MM Pro features a 16bit ADC that can achieve a dynamic range output of 14 stops. This improves the image sharpness and contrast significantly and the colour shades are smoother and more natural.

When the gain value is 100, the HCG high gain mode is automatically activated and the readout noise is greatly reduced while the dynamic range basically remains unchanged.

The ZWO PRO cameras incorporate a 256MB DDR3 memory buffer that improves data transfer reliability and it minimizes amp-glow caused by slow data transfer speeds.

The USB 3.0 Port provides 5Gbps bandwidth and lets the camera run at 3.51fps at full resolution (26 Mega). 

The USB 2.0 Hub allows to connect 2 USB controlled accessories such as a filter wheel, a guiding camera or an electronic focuser, reducing the amount of cables that run directly from your computer.

The 2 stage TEC cooling system allows a ΔT of 35°C below air temperature.

Note: All cooled ZWO cameras require an external power supply of 12V at 3-5A with a 2.1×5.5 mm connector (positive tip).

The dew heater avoids the problem of dew condensation on the optical window of the sensor. The heater can be turned off via software.

Traditional CMOS sensors produce a weak infrared light source that is often seen in the corner of uncalibrated images as bright glow. The ASI 2600MM Pro uses the zero amp glow circuits that avert this artefact in your images.

Another great camera from ZWO

Already owning the ZWO 2600mc pro it was not hard to justify the purchase of the mono version.
I had been using the ZWO 533mm for a year now to see how mono would work in my location with few clear nights.
The 2600mm has all the benefits of the 533mm but with the larger APSC sensor.
Very low noise, great signal and excellent build quality.
First image was the Skull and Crossbones nebula taken on a Skywatcher MN190 using Antlia 4.5nm Ha, O3 and S2 filters.
30 X 300sec each.
Very happy with the service and purchase.

Bought this from Adriano and am very happy with the service and fast delivery.
Camera is great and was easy to get back focus right by following the recommended spacing in the manual.
Works flawlessly with my capture software NINA. I have been trying it out a bit when the clouds aren’t around and have found that I don’t need bias frames when stacking in Pixinsight. Works great without them. Looking forward to getting some great shots for a long time to come. I’ve put a Picture of the Horsehead and Flame nebula that I took using it. Ha, G,B filters only as the moon was half full. The JPEG quality doesn’t do the picture any justice though.

As always top service by Adriano and camera got delivered in two days . Weather has not been the best but the 2600 mm is fantastic and easy to use and gives great results . I now have both OSC and Mono 2600 and very very happy with this cameras and the great service from Adriano.
