ZWO ASI071MC Color APS-C CMOS Cooled Imaging Camera

The ZWO ASI071MC uses the very popular Sony IMX071 APS-C sized color CMOS sensor, for true 14-bit dynamic range, low read noise of 2.3 - 3.3e, and a full well capacity of 46ke! This Sony 16.2 MP sensor has been used in several popular DSLR cameras, and will produce amazing results, whether you are using it to capture deep sky or planetary images. The Exmor sensor has an image array consisting of 4928 x 3264 pixels that are 4.8um in size, and features on-chip analog/digital signal conversion and two-step noise reduction in parallel on each column of the sensor.

The ZWO ASI071MC camera allows the sensor to be cooled to 35C to 40C degrees below ambient. Below are the extra features that can be found on the camera body, specifically related to the cooling feature:

  • Just below the USB hub (dual 2.0 Out and 3.0 In), you ll find a 2.1mm center positive input for a cooler power supply (not supplied). ZWO recommends 12VDC at 2A max
  • A huge heat sink, which is nearly 2/3 the size of the camera, is located on the side of the body
  • The top of the camera sports a MagLev fan, which utilizes the attraction of the magnetic levitation force for low acoustic noise, high temperature endurance, and long life.

The ZWO ASI071 camera body also sports a high speed USB Hub and a heated AR window. The included software is compatible with Mac, Windows, and Linux operating systems. Everything you will need to control your ZWO camera is available and easily downloadable in one centralized location on the ZWO website. Click here for ZWO Software Downloads.
