Camera Sensor

ZWO ASI 071 With Sony IMX071

The Sony IMX071

  • The most popular Sony sensor
  • APS-C(1.8″) Diagonal 28.4mm
  • 16M Pixel (4944x3284)
  • Very low read noise: 2.3 electrons at 24db gain & 3.3e the lowest gain setting
  • 14Bit ADC: provide a real 14bit Dynamic range
  • Electronic shutter: no vibration caused by a with mechanical shutter

DDR Memory Buffer

ASI071MC 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.

ZWO ASI 071 DDR Memory Buffer

DDR memory buffer is the main difference between ASI “Cool” and “Pro” cameras.

Astrophotography Performance

ASI071MC Pro offers very good performance for astrophotography. Low read noise, high dynamic range.

USB Port &Hub

USB 3.0 Port: Provides 5Gb bandwidth to make it possible for ASI071MC Pro to run at 10 fps (14bit, normal mode) at full resolution(16-megapixels)

USB 2.0 Hub: manage your cables by connecting various accessories like a filter wheel, guide camera or electronic focuser. There are two short 0.5m USB2.0 cables included with the ASI071 Pro. The hub is powered by the external power supply if you connect one.

New Mechanical Design

The ASI071MC-PRO camera comes with a completely upgraded anti-dew and mechanical body. The diameter of the camera body is increased to 86mm (ASI071MC-Cool is 78mm), and the new structure seals the CMOS chamber that prevents frosting.

ZWO ASI 071 Pro vs. Cool

anti-dew and cooling system

ASI071MC Pro has a two-stage TEC cooling system that allows deep cooling (35°C-40°C below ambient). You will need an external power supply to power the cooler. An AC-DC power adapter is not included in this package, however, you can order one 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 9-15V is also suitable for the cooler power supply. The anti-dew heater will heat the AR protect window to avoid any dew problems. The heat anti-dew heater power is around 3.6W and can be turn off in software to save power.
