Thanks again for all the helpful information! I see the benefit of going straight to the G11 instead of the G8, especially because I would probably want to upgrade to a G11 eventually. I¡¯ll just have to patiently save a little longer for it and practice with my current setup in the meantime.
I ran into the the DSLR back focus problem on my Newtonian with my DSLR. I ended up modifying the Focuser to achieve focus. Of course, I think my new dedicated astronomy camera will be able to achieve prime focus without the adapter (and without torquing the tube as much as the heavy DSLR).
