C9.25??

Hi,

I'm currently using a Vixen GPD2/ED80/Skywatcher FR/C QHY8 combo for imaging. This setup is proving so effortless to use (after years of fighting EQ6/newt combos) that I'm getting bored doing nothing on the rare nights in Melbourne when imaging is possible these days. I mean, I set it up, start the guiding/imaging process and there's nothing to do until it finishes! I'm thinking of getting a CPC9.25 for doing some visual stuff while the camera is ticking away. A friend has just bought one and it is a VERY nice scope, visually at least, and in Alt/ASz mode viewing is especially comfortable. It had been so long since I actually looked through a telescope that I had forgotten the pleasure that could be obtained.

My main query is related to occasional use as a long FL imaging scope. Anyone know what the field would be like at F10 on a QHY8? What about with an F6.3 reducer? Anyone know if the Allan Gee reducer11 is better than the Celestron one?

Just wondering whether much cropping would be needed to get round stars at the edge?

cheers
Gary
