Low read noise, Low dark current, high dynamic range . ASI1600 build in 12bit ADC but can provide 12.5 stops dynamic range which is even better than KAF8300 due to its super low read noise. ASI1600 Pro has 2 stage TEC cooling system to enable very deep cooling (40 Degree C-45 Degree C below ambient). The cooler requires an external power supply. Notice?Cooled ZWO ASI  cameras requires a 12v  power supply, which is not included with the camera. You need order a suitable power supply .
