new astronomy ccd press

Rowland, google search for the above, that tool lets you combine ccd spec and telescope spec to get a fov and arc/sec/pix result. I can't tell you you which is best. It's up to you to decide which one you like.

If I run that code here with a 50mm F4 lens and a qhy10 I get 6.28 arc/sec/pix and 271 arc min FOV.
