My wife just wont this scope as a door prize at a recent star party. Exceptional luck. Has us thinking about astrophotography again. I see it comes with two extension tubes as well as a diagonal. I'm taking some rough measurements of the 480mm focal length, and trying to figure out if, even with the two extension tubes, this thing will focus. Simple math would tell me that the focal plan will be 18.89" from the objective, but even with all the tubes in I'm not sure I can get there. May be OK for visual when adding the diagonal as that adds a few inches of travel.
Can anyone with one tell me how they set it up for visual and photographic use?
Wasn't sure if this should go here or in the AP forums, since it deals with both.
