The QHY268C has only 0.7 electron of read noise at highest gain and 6.8 FPS at full resolution readout speed. One electron of read noise means the camera can achieve a SNR>3 at only 4 to 6 photons. This is perfect performance when conditions are photon limited, i.e., short exposures, narrow band imaging, etc., making this large area sensor ideal for sky surveys and time domain astronomy.
Back-Illuminated, High QE
The back-illuminated Sony Exmor sensor has about twice the QE of similar front illuminated sensors. The QHY268C has zero amplifer glow. In addition the dark current is only 0.0005e/pixel/sec @ -20C.
