If it's a Newtonian you may run out of backfocus & can use a coma corrector if this happens. Check out "prime focus astrophotography" in google. You really want to be able to make 60 second shots & stack - not easy.

With your normal camera lens set to infinity, hold the camera behind the eyepiece (about 1/2 inch clearance) look thru your camera viewfinder and take the shot, adjust shutter speed for proper exposure (try 1/2 second).
