The QHY247C Cooled Color Camera uses a SONY IMX193 APS size color CMOS sensor. Pixel size is 3.91um and it has a 14-bit A/D with a full well capacity of 36ke-. It has 2.7e- read noise at lowest gain, 2.2e- read noise at unity gain (system gain = 1e/ADU), and 1.0e- at high gain. It’s ideal for stacking many short exposures. The IMX193 has excellent quality AR coatings on the sensor and this can significantly reduce the halo effect.

True Raw Data: QHY Cameras offer true raw image output and produce an image comprised of the original signal only, thereby maintaining the maximum flexibility for post-acquisition astronomical image processing programs and other scientific imaging applications.
Anti-Dew Technology: Based on almost 20-year cooled camera design experience, QHY cooled cameras have implemented a full dew control solution. The optic window has a built-in dew heater and the chamber is protected from internal humidity condensation. An electric heating board for the chamber window can prevent the formation of dew and the sensor itself is kept dry with a silicon gel tube socket design for control of humidity within the sensor chamber.
Cooling: In addition to dual stage thermoelectric cooling, QHY implements proprietary hardware technology to control the dark current noise.
As a result the dark current of the camera is 0.0012e-/p/s at -15C.
