Thanks for the replies, two OTAs seem to be the way to go, though this is going to increase both weight and setup time. I seem to be limited to a SCT for portability reasons and 8-10" by budget. The second tube a short 80mm ED refractor. Mount is not sure yet - GEM or Fork/Wedge though fork seems simpler to use and is less $$. What is the preferred method for attaching these tubes, I would want something faliry quick and easy to mount/demount?
