ZWO ASI662MM USB3.0 Mono Astronomy Camera - ASI662MM

The ZWO ASI662MM Planetary Camera is based on the Sony Starvis 2 IMX662 monochrome CMOS sensor, with 2.07 million 2.9 um pixels in a 5.6 mm x 3.1 mm (1/2.8") frame.  The ASI662MM has a rolling shutter, and in high speed mode it has an output at full resolution of 107.6 frames per second, with a low read noise level of 0.8e.  

Sony's STARVIS 2 technology offers higher sensitivity to red and near infrared (NIR) light.  Other features include zero amp glow, a full well capacity of 38.2e, and lower dark current noise.

The ZWO ASI662MM Mono Camera is equipped with a USB3.0 transmission interface and a built-in 256MB (2Gb) DDR3 cache to ensure stable and secure data transmission.  This camera also exhibits zero amp glow, regardless of the exposure length or gain value.  This zero amp glow feature is implemented at the hardware level and does not require software control.

Readout noise consists of pixel noise, ADC quantization noise, and circuit noise.  The lower the read out noise the better your results will be.  This CMOS camera has much lower readout noise than a CCD camera.  The built-in HCG mode effectively reduces the readout noise at high gain and keeps the dynamic range at the same level it was at low gain.  Once the gain reaches 252, the HCG Mode is automatically turned on and the dynamic rises back to 12-bit (see the camera curve chart in the image carousel above).
