Description
QHY695A -
6mega pixel 1-inch high QE astronomy CCD camera
QHY695A uses the ultra-high sensitivity SONY ExView II CCD sensor ICX695. This sensor has a QE close to 80%. The readout noise is as low as 4 electrons. With the two stage TEC, cooling to -45C below ambient and the extremely low thermal noise of ccd sensor, this camera produces a very clean image. This camera has built-in 7-position 36mm unmounted filter disk, providing plenty of capacity for LRGB, Ha, OIII, and SII filters in it at one time. Comparing with the five or six position filter disks, this camera will make LRGB and narrowband imaging much easier. Although the sensor has electric shutter, this camera still has a mechanical shutter installed, allowing the user to perform automatic dark frame capture.
1-inch CCD - ICX695
Sony ExView II sensor is well-known for its low readout noise,low thermal noise and high QE. The pixel size is 4.54um and total 6mega pixels.
"A" Series Camera - Fully Integrated
Both QHY695A belongs 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 QHY695A is a 7 position wheel designed for unmounted fitlers. The camera compatible with the medium size QHYOAG.
Besides the filter wheel and OAG, "A" series camera has more to offer. An internal USBHUB(2.0) provides two USB host port and a USB to dual RS232 coverter. 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 needed from the camera to the computer.
Butterfly Shutter - unlimited life and uniform illumination
This camera uses a butterfly mechanical shutter. This shutter is driven by motor directly and it is only one piece, resulting in no friction with other components. The working life is almost unlimited. This shutter has two sides to cover the light. This shutter allows for uniform illumination of the chip.
Single 12V power socket
This camera uses the single 12V to power. The power socket has a thread, it can connect with the DC plugs with thread lock to get a solid connection. There is another socket which is connected with the input in parallel. It can supply 12V to other devices nearby.
