At f/22.5, ~how many pixels was Mars occupying in your imager?
I have a Neximage 5 that was I was going to use with my C 8SE (non-Edge, alas) at f/25 (using a 2.5x PowerMate), and so was curious what I might expect. I just need to get a darned clear night!!
For further info (for my benefit

) what resolution and how many frames?
