"A" Series Camera - Fully Integrated
Both the QHY16200A and the IC16200A 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 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 filter wheel in the QHY16200A/IC16200A has 5 positions for 2-inch filters (QHYCCD is developing the 7-position 2 inch filter wheel upgrade). The camera is compatible with the medium size QHYOAG. In addition to the filter wheel and OAG, this "A" series camera offers 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.
Butterfly Shutter - long life and uniform illumination
This camera uses a mechanical shutter that has a butterfly shape. 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 create 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.
Sensor Early Testing (July 2015)
We received some engineering grade sensors from the supplier and performed early testing. Here are some results under real sky conditions. We were just testing sensor performance, and not attempting quality images as the camera was a very early prototype and the optics of the small 4" scope were not well aligned. Nevertheless, here are the first samples:
Single 12V power socket
This 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.
Industrial USB Socket
USB is designed for use with commercial electronic devices. It is not a particularly robust and the contact can cause the USB transfer to hang if it pulls out due to telescope motion, etc. In the "A" series design QHYCCD provides a unique stainless steel USB cable clip to improve the reliability of the USB connection.

In addition to our own test images, in 2016 we sent several cameras out for beta testing. These cameras also used engineering grade sensors. Here is a sample image by beta tester user James Shimoji. Full size image download (32MB)
