Or is a lens mounted on the SLR and piggy backed onto the eyepiece? Anymore information about choosing the right FILM SLR would be appeciated thanks
Most often, the camera is mounted to the telescope directly, using the scope as a telephoto lens. You can also do afocal (camera lens to eyepiece) and eyepiece projection ( using the eyepiece to project a more magnified image onto the film). Any basic book on astrophotography will describe the specifics.
Desirable characteristics for the camera include mechanically operated shutter (so it doesn’t run the battery down keeping the shutter open), mirror lockup, and interchangeable focus screens. The Olympus OM1 in 35mm and the Pentax 6×7 in medium format have been very popular.

Any camera can be adapted to the eyepiece of an amateur telescope using a T-mount adapter and suitable T-mount to eyepiece adapter. My setup cost me about $50 and I can use any of my Nikon 35 mm SLR’s or DSLR’s.
I now use a D300 using the "live view" mode to fine tune the shot before taking it. You will need a motor driven telescope to track the subject of your nights shooting to correct for the earth’s movement and rotation during the long exposures necessary to capture all celestial objects but the moon.
