Taking the advice from everyone, I think that I will go with an atlas and a shorter focal length scope with my dslr, then move onto a CDC and bigger scope latter.
The two that I've been looking at are the at6rc and the at65edq. I chose these two because they seem to be very good based on the reviews and they are cheap enough so that I won't have to sell my 12"
Go with the AT65EDQ in that case. The AT6RC while lighter is still a difficult scope at f/9 and some people really struggle with it, particularly if there is a collimation issue. I think that the EDQ also has a better focuser.
