QHYCCD Medium Size Cooled USB 3.0 Planetary and Deep Sky COLDMOS Camera. 16 Megapixel CMOS sensor!

The QHY163M/C camera is an incredible value. It uses a relatively large 4/3inch, 16 Megapixel CMOS sensor, available in both monochrome and color. The QHY163M/C has exceptionally low readout noise (as low as 1 electron!), low dark current and two-stage cooling capable of reducing the sensor temperature to -40C below ambient. The sensor chamber is sealed and the optical window is heated to prevent dew. The camera’s interface is USB 3.0 and delivers 23FPS@16 megapixel full resolution output, 30FPS@4K HD video output.

128MB DDRII Image Buffer

QHY163C has a built-in 128MB DDRII image buffer. The benefit of the image buffer is that the memory will cache the image and transfer it to the computer when the USB interface is not busy or being interrupted, and the frame will not be lost or corrupted. This buffer also allows a slower computer with USB 2.0 socket to capture every frame without loss even if the USB socket is occasionally busy with other peripherals. This buffer also helps multiple camera applications and avoids USB transfer problems. For example, it is possible to operate four QHY163M cameras on the same computer to create an LRGB imaging array.

Anti-Dew Technology

With more than a decade of experience designing cooled cameras, QHYCCD has applied this knowledge to the QHY163 camera. The full anti-dew technology includes a sealed CMOS chamber with silicon gel tube socket and a heated chamber optical window. This technology prevents dew from forming on the sensor itself, or on the chamber window, even in a high humidity environment.

Performance Chart

It is very important to understand the “unity gain” concept for CMOS Cameras and select a suitable gain for capturing. The unity gain is the gain position that the system gain is 1e/ADU. At lower gain settings, the system gain will exceed 1e/ADU and this will cause the sample noise. The QHY168C unity gain setting is 10.

For DSO capture, there are two capture methods.

          1. One is the traditional long exposure DSO capture,
          2. Another is the Lucky imaging method with a short exposure and high quantity stacking.

For the long exposure, you can use the lower gain to avoid the image get saturated. For lucky image, you need to use high gain to reduce the readout noise and avoid the sample noise.
