QHY9 is a classic mono camera using the very popular 8.6mega pixel KAF8300 CCD sensor. This sensor has a good QE for deep sky imaging. The peak QE is 56% and it has 48% QE in H-alpha wavelength. The 4/3 inch size makes it works well for most telescopes.
QHY9 has two stage TEC and typical delta T is -45C below ambient. It offers outstanding thermal noise control. To compare with those camera with -25 or -30C cooling, QHY9 give you more clear image even in very long exposure time no matter in hot summer or in cold winter.
QHY9 has very low readout noise between 8300 based camera.
