QHY9000A "A Series" CCD Camera with Integrated 7-Position Filter Wheel

Starting Price: $10,560.00
Price as Configured: $10,560.00
Brand: QHYCCD / SKU: QHY9000A

The QHY09000A cameras is a 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.

“A” Series stands for “ALL-IN-ONE”. The camera includes a built-in motor driven filter wheel and natively supports the QHYOAG while consuming a minimum of back focus, precious for some optical systems.

In addition to the filter wheel and OAG, the “A” series camera also offers an internal USB2.0 hub providing two USB host ports and a USB to dual RS232 converter. A guiding camera, mount and electric focuser can be connected directly to this camera instead of the computer to reduce cable clutter and the chance of signal loss due to the long cables. A single USB cable controls all of the peripherals.

The camera uses a single 12V IN power port. The power socket is threaded for a solid connection that will not accidentally disconnect. There is another socket connected in parallel with the input that can be used to supply 12V OUT to other devices.

Each “A” series camera has a mechanical shutter that has a butterfly shape for automatically capturing dark frames. The shutter is directly driven by a motor with no other moving parts. The working life is almost unlimited. The shutter has two sides that block light and open spaces in between. The fan shape of the blades creates even-illumination when opening, and even-darkness when closing for dark frames. This feature is of great benefit when taking flat frames or making photometric observations.

The QHY9000A camera uses 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.
