With the advantage of low readout noise and high-speed readout, CMOS technology has revolutionized astronomical imaging. A back-illuminated, high-sensitivity, astronomical imaging camera is the ideal choice for astro-imagers. The QHY600 uses the Sony IMX455, a full frame (35mm format), back-illuminated sensor with 3.76um pixels and native 16-bit A/D. This sensor is available in both monochrome and colour versions. The QHY600 ends the days of non-16 bit CMOS cameras.

Models

The QHY600 Series have multiple models which cover both photographic and scientific uses. There are two variants that apply to astrophotographic uses:

QHY600PH : Standard version for amateur astrophotographers;
QHY600PH-SBFL : it has shorter back focal length compared with other PH types

In addition, there is a “lite” version of the QHY600 available as a separate product.

Effective Pixel Area	95766388 （96006422 with overscan and optically black area)
Effective Pixels	61.17 Megapixels (Effective area)
Sensor Size	Full Frame 36mm x 24mm
A/D Sample Depth	16-bit (0-65535 levels) at 1X1 binning 18-bit at 2X2, 19-bit at 3X3, 20-bit at 4X4 software binning QHY600 uses the software digital binning for 22binning. With digital sum, 2*2binning will be four 16-bit summed then it is 18-bit.

Exposure Time Range	40us – 3600sec
Unity Gain*	25 (Extended Full Well Mode) * *With the improvement of the CMOS technology, the 16bit CMOS camera has been released, like QHY600. For these cameras, even in lowest gain it has beyond the requirement of unit gain (less than 1e/ADU due to sufficient samples) So you can directly set gain 0 as start. Please note QHY600 has extend full well mode. In this mode you still need to find out the unit gain position.
