Out of stock

QHY128C is a full-frame , 24mega pixel , one-shot color CMOS camera with 5.96 um pixel size and 14bit ADC. Very low dark current (0 0006e ps @ -15C) , very low readout noise (1e to 4e) and 74ke large full-well.

The QHY128C is one of the top-performing cameras in the COLDMOS line. In the QHY128C this sensor is implemented specifically for astronomical use with custom thermal noise reduction technology.

Main Features:


In the DSLR implementation, there is a RAW image output, but typically it is not completely RAW.  Some evidence of noise reduction and hot pixel removal is still visible on close inspection.  This can have a negative effect on the image for astronomy such as the “star eater” effect.  However,  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 an almost 20-year cooled camera design experience, The QHY cooled camera has implemented the full dew control solutions. The optic window has 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 our silicon gel tube socket design for control of humidity within the sensor chamber.



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 the camera is 0.0006e-/p/s at -15C.
