I have for sale a QHY22 Mono Camera in excellent condition. It uses the very high QE (~80%) Sony ICX694 sensor with very low read noise (5e-). It cools to 45°C below ambient so it can run at -25°C all year round. The frames are so clean the use of dark frames is not required. Please see attached images which are taken with lights, bias and flats only. Comes with usb cable, DC201 with 9 pin power cable, cigarette adapter cable with switch, cable binder and pelican hard case.
Price is $1800 (which includes shipping and insurance Australia wide)
