For a really long time the 8300 Monochrome sensor has been the goto sensor for many an astrophotographer. QHYCCD company also employs this sensor in the now Classic QHY9M Monochrome camera. Below is a really quick review of teh camera
1)An absolute brilliant piece of equipment for a far lesser price than competitors.
2)Ample pixel size for most telescope to get good sampling.
3) -50C below ambient cooling eliminates darks.
4) the filterwheel accomodates a variety of filters based on users choice.
This review is after four years of use and it still thrills me everytime I use this nice camera.
