hi Col
At this stage, my main preference is planetary imaging, so that's why I upgraded to a bigger newt (12") and the EQ6 (more accurate tracking). The 10" dob on EQ platform was great at the time, a great mix of visual and ability to do solar system photography, but I'd reached the limit of what I could do with it. The 12" gave me extra aperture and focal length, just what I needed.
I still love visual, but I mainly do observing from our new moon meets at Kulnura with mates like Rod and his 20" SDM, so why would I use mine for visual when I can observe through an awesome 20" scope!?
I loved my 10" dob on EQ platform, and really regretted selling it and would have no hesitation in recommending that setup to anyone else. But for the imaging I want to do, the 12" on EQ6 is a great (but heavy) combination.
For visuall, newts on EQ mounts can be quite clumsy with the eyepiece getting in strange positions. Especially with such a long tube like the 12". I wouldn't recommend a 12" newt on an EQ6 for visual use.
