I'd like to thank everyone for their input into this topic. I certainly have some things to consider.
I think I will almost definitely purchase an AN, if for nothing else, for my Dob(s).
I also think I may try the astrophotography mount in a stand-alone configuration initially. In retrospect, the goto/pushto functions allow you to find the target initially, but after that do not improve tracking/guiding accuracy. The guiding control feedback loop is probably more important.
After my (limited) experience with the dobs, I can find many of the larger targets quite manually. And, with a TV Genesis at 500mm FL as my imaging optic, I am in relatively widefield mode.
If I later decide to put on a longer focal length imaging optic, I will perhaps revisit the initial pointing issue.
Many thanks again to all those who have contributed.
Brian
