The QHY294C uses a 4/3-inch back-illuminated cooled color CMOS sensor, 14-bit A/D. 6,8e readout noise in lowest gain, 1.6e- read noise near unity gain and 1e- read noise at highest gain. At USD999 retail price the QHY294C is a very good camera for you to begin your deep sky imaging. This camera is a dedicated cooled camera with high performance for both QE, dark current and readout noise.
The QHY294C produces 16.5 high resolution frames per second, 11.6 Megapixels with 14-bit A/D. Higher rates are achieved in ROI mode, for example, 41 FPS at 1080 lines.
The QHY294C uses QHYCCD's proprietary low dark current control technology. This technology significantly reduces the dark current noise in our CMOS cameras. The QHY294C has super low dark current as a result, lower than many CCD cameras
eras, allowing for very long exposure times.
