ZWO ASI1600MM-PRO

Astrophotography Performance
ASI1600 Pro offers very good performance for astrophotography. 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.

DDR memory buffer
ASI1600 Pro camera includes a 256MB DDR3 memory buffer to help improve data transfer reliability. Additionally, the use of a memory buffer minimizes amp-glow, which is caused by the slow transfer speeds when the camera is used with a USB 2.0 port.

Reliable Mechanical Structures
There are four screws that seal the sensor chamber. Our camera design has been extensively tested and is very stable. Even when used in higher humidity environments, ASI1600 Pro will still works fine without dew problems.

USB 3.0 Port & USB2.0 HUB
USB 3.0 Port: Provides 5Gb bandwidth to make it possible for ASI1600 Pro to run at 14.7 fps (12bit, normal mode) or 23 fps (10bit, high speed mode) at full resolution (16Mega).
USB 2.0 HUB: Can connect with various accessories,  including a filter wheel, guide camera or electronic focuser, allowing you to manage your cables better. There are two short 0.5m USB2.0 cables included with the ASI1600 Pro. The hub is powered by the external power supply if you connect one.

Cooling System
ASI1600 Pro has 2 stage TEC cooling system to enable very deep cooling (40°C-45°C below ambient). The cooler requires an external power supply, which is not included with the camera. You may order a suitable power supply from here.
We recommend using a 12V/3-5A or more DC adapter for cooler power supply (2.1×5.5, center positive).
Using a battery with 11-15V is also suitable for the cooler power supply.
