JasonB - I have asked for an 8" and a 10".
MikeBOKC - Not sure on the mount yet. I would suspect a G11 class would work well, but you know how you nutty astro-photographers can get. lol

How would these scopes perform for visual use?

I just bought GSO 12" Carbon RC and found that attaching the focuser directly to main mirror is a design flaw. that kind of design makes too much stress for main mirror, perhaps not for DSLR but a CCD and a filterwheel is too much.
Im not sure, but does this one has same design?

P.S. New images and specs are up here: https://www.astronom...cal-tube_p20...

AT12RC steel tube with no focuser - 49.3 lbs
AT12RCT truss tube with 2" focuser - 52 lbs
Clearly weight won't be a reason to choose the truss model.
So assuming I'm reading the specs correctly for the additional $500 it appears you get a very unique looking scope, a 2" crayford focuser, less temperature induced focus change, and perhaps somewhat better cool down characteristics ... anything else?

I would say the cooling will be much better then somewhat. The open tube should allow a much more efficient cooling time when combined with the Quartz optics.

We will also have the 10" in a truss shortly and I asked about making an 8" truss.
