Here are some images showing the placement of the guide camera, the available movement in the focuser around where I hope I can get the dslr to focus, and the amount of protrusion into the main tube at this location.
I was assured before I bought the scope that it had plenty of back focus to accomodate my camera focus requirements. Oddly enough though though, when I tried focusing with the supplied 2” eyepiece, I had to pull it out to the extreme of it’s length, and with the focuser all the way out. So it seems its from one extreme of the focuser travel to the other between visual and AP, unless I’m doing something wrong trying to get the camera in focus?
