MPCC and QHY8
There's been some good discussion happening about the QHY8 lately which has sparked this question: can a MPCC be used in place of a field flattener?
I use a MPCC with my Newtonian and also a QHY8 - with a spacer from Peter Tan to maintain the 55mm separation between imaging plane and the MPCC. I'd like to use the QHY8 on other scopes - my new ED127 for example or even my GSO RC. So I am wondering whether I need to remove the MPCC before I do or whether I can keep the whole shebang together (perhaps even my whole OAG setup) and move it from scope to scope.
