Yes, I am going to get QHY2 as an imager specially for deep sky imaging. QHY2 is designed by Dr.Qiu Hong Yun, a PhD of Precision Measurement Technology and Instrument from Beijing Tsing Hua University.
What makes me choose this over Meade DSI II? Let me reveal it when I have it in my hand. ![]()
The CCD of QHY2 is changeable. Therefore, it’s possible for you to opt a higher sentivity monochrome CCD with filter wheel and filters. Now, I’m going to get it with the original colour CCD. It’s the ICX412, a Sony Super HAD CCD that has 3.3 mega pixels in 1/1.8″ CCD array. Its pixel size is 3.45*3.45 which is small enough to tame the short focal length telescope.
(Hey wait, mine is a long one.. Got to get a focal reducer!)
I will do a review on this imager once I have received it, the estimated arrival time is October May June 07. QHY is designing a new case. The new case is done. It’s the one at the right on the picture above.
Edited:
1. Wrong CCD version, it should be ICX412 (2X sensitive of ICX262)
2. Designation given to QHY as he is now a PhD. Congratulations!

3. Some minors changes made.
