Description
QHY268M Mono CMOS Camera is a cooled, back-illuminated, CMOS camera based on the Sony IMX571 sensor with native 16-bit A/D and 3.76um pixels. This is the Mono version of the popular QHY268C colour camera.
The camera has a newly designed front end giving a BFL of 12.5mm
The QHYCFW3-M-US and QHYOAG-M are compatible and it’s easier to use 1.25″ format guide cameras like the QHY5L-II Mono
