Newtonian DSLR Adapter

I have a Celestron SP-C6 Newtonian which I an trying to mount a DSLR camera to. I purchased a Celestron T adapter and ring for my Nikon D5100 camers. The problem is, the tube is too long. To focus, the camera needs to sit almost right on top of the telescope tube. Is there an adapter that I can purchase that is short enough? Thanks in advance. I'm a real newbie!

Unfortunately most commercially made newtonian scopes place the image pretty far out in the focuser. The only really good way to access prime focus is to move the mirror and cell in the needed direction so the camera will reach focus. This is not hard to do if you are careful. Simply remove the mirror cell with mirror and redrill holes to mount the mirror and cell in. Usually about 1.5 inches forward in the tube will be enough. You might also consider replacing the focuser with a 2" variety if it doesn't have one already.
