ZWO ASI071MC Pro Color Astronomy Camera

ZWO's ASI071MC Pro Camera uses the Sony IMX071 sensor in the color format. It features a fully upgraded mechanical body with anti-dew properties widened to 86 mm, even wider than the popular ASI071 which was 78 mm in diameter. The chamber is sealed via 6 screws. This design improves the CMOS chamber seal to prevent dew or frost from affecting the sensor. Air leaks are not an issue, and the camera maintains its dryness in any environment.

With low read noise and high dynamic range, this camera offers exceptional performance for astrophotography. The PCB board on the ASI071MC Pro has also received an upgrade. Compared to the Cool version, dark current noise has been drastically reduced and is now similar to a CCD camera.

Cooling System

The ASI071MC Pro Color Camera features a two-stage TEC cooling system for extremely deep cooling at -35ºC below ambient. An external power supply is required in order to operate the cooler. An AC-DC adapter is not included with this package, but can be purchased separately.

Anti-Dew Heater

The protect window is heated by the anti-dew heater to avoid any dew problems. Heat power is approximately 6 W and can be switched off via software to save power.

DDR Memory Buffer

For improved data transfer stability, the ASI071 Pro has an integrated 256MB DDR3 memory buffer. This also eliminates amp-glow issues commonly caused by slow speed data transfer during readout with USB2.0 ports. The DDR memory buffer is the key distinction between ASI "Pro" cameras and ASI "Cool" cameras.
