Thanks Jared. I figured I'd probably have to go to an OAG. The 8" f/4 guides great with a guidescope but it's only 800 mm.

I just got my AT10RCF a few weeks ago and this last weekend was my "first light" with the scope. Initially the collimation was pretty far off (relatively speaking) and I got a Hotech SCA laster colimator that other said would work... but that failed. So I did it the old fashion way of defocusing the star and doing it visually. While not really spot on, it was better then what got shipped. Initial images were ok, but I know it needs a lot more work.

I'm not using an SBIG model 8300 on this scope, but rather the QHY9m (but its still an 8300 based camera). I may switch my STT-8300 over to it and off the AT106.

I'm hoping not to have to use an OAG because I have never really had good luck with them. Instead I am going to use my AT106 (704mm FL) as the guide scope. Its a good solid mount on a Paramount MX, and the only thing I will need to watch for (hopefully) is sag in the image train between the two scopes.

Anyway, just thought I would put in my $0.02 on this scope and camera option. I think I will really like it once I get it setup properly.
