The QHY16803A camera is large format astronomical CCD camera using the well-known 16 Megapixel KAF-16803 CCD , popular with both advanced amateurs and professionals. The image area is just over 36mm x 36mm for sensor. The camera use an evenillumination mechanical shutter for photometric quality darks and flats. This shutter is operated by direct drive and has an extraordinarily long life with no other moving parts.
The KAF−16803 image sensor is a redesigned version of the popular KAF−16801 image sensor (4096 (H) ×4096 (V) pixel resolution), with 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. When combined with large imaging area and small pixel size, the KAF−16803 provides the sensitivity, resolution and contrast necessary for high quality digital astro-images.
"A" Series Camera - Fully Integrated: The QHY16803A belong to the new QHYCCD "A" series camera family. "A" stands for "ALL-IN-ONE". The cameras include a built-in motor driven filter wheel and natively support the large size QHYOAG. The OAG can be installed on the camera solidly with six screws, consuming a minimum of back focus, precious for some optical systems. The built-in filter wheel has 7 positions for 50mm square filters. The "A" series cameras have an internal USB HUB(2.0) that provides two USB host port and a USB to dual RS232 converter. A guiding camera, mount and electric focuser can be connected directly to the camera instead of the computer to reduce cable clutter and the chance of signal loss due to the long cables. Only a single USB cable is needed to control all the peripherals.
