Ashley,,, TREES.. Your telescope will have a totally diferent focus spot when looking at the night sky. Seeing your MPCC will fit down the focuser draw tube it may pay to fit the MPCC to your camera and while holding it, move it into the drawtube with the draw tube fully in and see if you can reach focus. If not try it the other way even if it is outside the drawtube. By focusing this way you should be able to find which way you need to go to reach focus and roughly by how much.
Just a note. If it is the 10" you are working with, you may be in a position I was in a few years back. My only way to focus the camera in the Dob was to cut 48mm off the bottom of the Dob tube and reposition the primary mirror. Balance will then be out. An added weight was needed to balance the Dob again.

Good Luck
