Now, I was thinking of putting my 16" on an equatorial table and having a go at some widefield imaging.

However, just out of interest, I got an adapter for my 400d and found I cannot get the camera into focus, as I suspected would happen.

Question: Is there any way I can get the camera into focus WITHOUT moving the primary lens up the tube? I still want to use the Dob (16" LB) for visual observing.
