QHY695A/IC695A -
6mega pixels 1-inch high QE astronomy CCD camera
Status: In stock

QHY695A/IC695A 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 electron. With the two stage TEC, -45C below ambinent and the extremly low thermal noise of ccd sensor, this camera brings a clean image to you. This camera has built-in 7 position 36mm umounted filter disk or 8 position 1.25inch disk. You can fill the LRGB Ha OIII SII filters into it at one time. To compare with the five or six fitlers disk, this camera will make LRGB and narrowbanding imaging much easy. Although the sensor has electric shutter. This camera still has a mechanical shutter installed. This mechanical shutter can be used for automaticly dark frame capture. Therefor It maybe use for some funny things, like cover the light when guide error is too big to avoid the star drift during long exposure

1-inch CCD    -   ICX695

"A" Series Camera - Fully Integrated
Both QHY695A and IC695A 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 QHY695A/IC695A is 7 positions 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 to rule them all.
Butterfly Shutter - unlimited life and uniform illumenation
This camera uses a mechanical shutter looks like butterfly shape. This shutter is driven by motor directly and it is only one piece with no friction to others. The working life is almost unlimited. This shutter has two side to cover the light. One is left to open the shutter. and another is enter to close the shutter. It has a uniform illumentaion feature.

Single 12V power socket
This camera uses the single 12V to power. The power socket has the thread, it can  connect with the DC plugs with thread lock to get solid connection. There is another socket which is connected with the input in parallel. It can supply the 12V to other device nearby.
