Description
8.6mega pixels 4/3 inch astronomy CCD camera
The QHY90A uses the popular 4/3inch CCD sensor KAF8300. This camera has a built-in 7-position color wheel for 36mm unmounted filters and a butterfly uniform illumination mechanical shutter.
KAF8300 - Popular Sensor
The KAF8300 8.3mega pixel 4/3 inch mono sensor is used in many astronomy camera models.
"A" Series Camera - Fully Integrated
The QHY90A belongs to QHYCCD's 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 the QHY90A/IC90A is a 7-position that accepts unmounted 36mm filters. The camera is 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 ports and a USB to dual RS232 converter. Your guiding camera, mount, and electric focuser can be connected directly to this camera instead of your computer to reduce cable clutter and chance of signal loss due to long cables. Only one USB cable is necessary to connect to the computer.
Butterfly Shutter - unlimited life and uniform illumination
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 a single 12V cord to power. The power socket is threaded, it can connect with the thread lock on the DC plug to ensure a solid connection. There is another socket which is connected with the input in parallel that can supply 12V to other nearby devices.
