Check my head on this... I'm a visual observer getting into AP with a primary interest in lunar and globs. I want great quality prints up to 38"x50" (120dpi minimum). I use a Canon 5dsr for terrestrial and have used it with a 400mm for AP on my EQ6r pro mount.
Inspired by Tom Glenn's lunar photo from January, I'd like to create a very high quality photograph (multi-frame composite) of the moon.
If I pick up a 9.25 edge hd, I'd like to, for now, use my Canon 5dsr and the eq6r. This would be oversampled at .36 as/p. I also have a 5d mk2 which has a larger pixel and would decrease the sampling to .56 as/p. (Would that be better?) At some point, I'd likely get an ap camera.
I would also be using this scope for lunar juxtapositions against the landscape so I'd likely pick up a (lighter, more portable) alt-az mount as I wouldn't need tracking for these shots, but would possibly need to move the tripod quickly from one place to another to compensate for some azimuth error. I might also use this set up for visual. If I prefer this over my 10" dob (I understand the only significant difference is the fov and dew), I might consider selling it.
Does this sound like the best value path for what I'd like to do? I know everyone says to start with a short FL refractor, but I have my 300 and 400mm lenses for that, and I don't have much interest in wide field. I've done a few so far and have had enough success with my tests, that I feel I'm ready to take the next step.
