I have an AO-LF sitting here waiting for my Atlas to arrive. I'll be putting them both on the GSO RC10. Without the Atlas I don't have enough back focus to make everything fit.

Rick do mean back focus or inwards focus ? With the extension rings for the gso I am surprised back focus is an issue? I would have thou go inward focus travel may be with sx ao, plus filter wheel plus camera etc...
