Focusing...

Hi all! I finally got a clear night in St. Louis last night and got a chance to take some astrophotos. I've been taking only piggyback photos, but I thought I would try coupling my OM-1 to the telescope (an Orion SVP 8") and see what would happen. I've heard that focusing is one of the most difficult tasks in prime focus astrophotography. I was able to view (pretty clearly) the Orion Nebula through the camera's viewfinder and bring it into focus. My question is this...if I can focus the image through the camera's viewfinder, is the image going to necessarily be focused on my prints/slides? It just seemed too easy, and too good to be true. Thanks!

Micheal,
Probably not. I could go into alot of detail here, but I'll just point you to some good information instead.
