Description
8.6mega pixels 4/3 inch astronomy CCD camera
QHY90A uses the popular 4/3inch CCD sensor KAF8300.This camera has built-in 7 position color wheel for 36mm unmounted filters and a butterfly uniform illumination mechanical shutter.
KAF8300 - popular sensor
KAF8300 8.3mega pixel 4/3 inch mono sensor is used in many astronomy camera models.
"A" Series Camera - Fully Integrated
Both QHY90A belong to QHYCCD new "A" series camera family. "A" stands for "ALL-IN-ONE". It includes a built-in motor driven filter wheel and it natively supports the QHYOAG. The OAG can be installed on the camera solidly with six screws at minimum back focus, precious for some optical systems.
The filter wheel in QHY90A/IC90A is 7 positions for unmounted 36mm filters. The camera compatible with the small size QHYOAG.
Besides the filter wheel and OAG, the "A" series camera has more to offer. An internal USBHUB(2.0) provides two USB host port and a USB to dual RS232 converter. Guiding camera, mount and electric focuser can be connected directly to this camera instead of the computer to reduce cable clutter and chance of signal loss due to the long cables. Only one USB cable is necessary to connect to the computer.
Butterfly Shutter - unlimited life and uniform illumenation
This camera uses a mechanical butterfly shutter that is frictionless. The working life is almost unlimited and provides uniform illumination of the sensor.
Single 12V power socket
This camera uses the single 12V to power. The power socket has the thread, it can connect with the thread lock on the DC plug to get a solid connection. There is another socket which is connected with the input in parallel that can supply 12V to other nearby devices.
