The QHY814A uses the Sony ICX814 ExView II CCD, a 1-inch, 9.2 megapixel sensor with a peak QE close to 80%. The read noise is as low as 4 electrons. The two-stage TEC, reducing the sensor temperature to -40C below ambient, and the extremely low thermal noise of this CCD, combine to give this camera its legendary clean images. 

The QHY814A has a built-in motor driven filter wheel for automatic sequencing of color or narrowband imaging. It supports both an 8-position, 1.25-inch filter carousel and a 7-position, 36mm filter carousel making it possible to install an entire deep sky filter set LRGB\Ha\OIII\SII at the same time. 

The QHY814A has very low read noise, typically around 4e-.  Compared to currently available monochrome CMOS Astrophotography Cameras, the QHY814A is a perfect camera for imaging deep space objects.
Although the CCD chip has an electronic shutter for short exposure timing, the QHY814A camera also has a mechanical shutter for automatically capturing dark frames. 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.

This camera belongs to the QHYCCD "A" Series camera family. "A" stands for "ALL-IN-ONE". The camera includes a built-in motor driven filter wheel and natively supports the QHYOAG while consuming a minimum of back focus, precious for some optical systems. The filter wheels available for the QHY814A accept 1.25" mounted filters, or 36mm unmounted round filters, in 7 or 8 position carousels.  Please contact us if you would like to request the 7 position carousel.
