The QHY09000A cameras is large format astronomical CCD camera using the well-known 9.3 Megapixel KAF-09000 CCD.

The image area is just over 36mm x 36mm for both sensors. This model has a seven position built-in motorized filter wheel that holds 50mm x 50mm square filters needed for this sized CCD.

The camera use an even-illumination mechanical shutter for photometric quality darks and flats. The KAF-09000 image sensor is a redesigned version of the popular KAF-16801 and a brother to the KAF-16803 but with larger pixels in the same size package.

The re-design included enhancements that specifically target the needs of high performance applications. Improvements include enhanced quantum efficiency for improved DQE at higher spatial frequencies, lower noise for improved contrast in areas of high density, and anti-blooming protection to prevent image bleed from over exposure in regions outside the area of interest.

The sensor utilizes the TRUESENSE Transparent Gate Electrode to improve sensitivity compared to the use of a standard front side illuminated polysilicon electrode, as well as microlenses to maximize light sensitivity.
