QHY9 is a classic mono camera using the popular 8.3 Mpixel KAF8300 CCD sensor.
This sensor has good overall QE for deep sky imaging.
The peak QE is @56% and it has 48% QE in the H-alpha wavelength.
The 4/3 inch size makes it well suited to many telescopes.
The QHY9 has a two stage TEC, and with typical delta T is -45C below ambient.
It offers outstanding thermal noise control. Compared with other models with -25 or -30C cooling, the QHY9 will give you a cleaner image. Even with long exposure times over those, hot summer or cold winter nights.
The QHY9 has very low readout noise as well compared with other 8300 based cameras.
The QHY9 has a sleek round design and is suitable for Hyperstar telescopes.
