The Sony Exmor IMX094 CMOS sensor is also found in the Nikon D800/810 DSLR cameras. This sensor is implemented in the QHY367C Pro specifically for astronomical use with QHYCCD thermal noise reduction technology. With read noise as low as 2.4e-, full well capacity of 56ke-, and 14-bit A/D, the camera has a dynamic range of more than 14 stops.
Many cameras claim to output RAW image files, but there is often still some internal processing performed on the image. This can have a negative effect on the image for astronomy such as the "star eater" effect. QHY367C Pro outputs TRUE RAW data, preserving the original data for maximum compatibility with astronomical imaging processing programs and other scientific imaging applications.
In addition to dual stage TE cooling, QHYCCD implements proprietary technology in hardware to control the dark current noise. As a result the dark current of this camera is a remarkable 0.0015e-/p/s at -15C.
The optical window has high quality AR+AR multi-layer coatings. In addition the sensor surface is AR coated, all of which significantly reduces halos around bright stars. IR blocking is not present, so that the cameras can be used with maximum sensitivity to H-alpha and near IR when desired, or a simple IR blocking filter (L filter) can be attached for typical RGB imaging with IR cut.
