There has always been some confusion as to the correct Back Focus for the Meade FR/6.3. What complicates thing for me is, i am using a Meade zero shift focuser as well.
So do you think I can get away with the following arrangement:
Visual back, FR/6.3, Meade zero shift Focuser, ASI294.
I have found imaging problems when i have used the following arrangement (and it still does not give me clearance thru the forks)
Visual back, FR/6.3, Meade zero shift Focuser, 2"Diagonal, ASI294.
I have thought of modifying the FR so it screws on to a standard 2" nose barrel. that way It could slide into the Focuser thus eliminating the space taken by the FR when screwed onto the Visual Back.
