This might be a good reason for a secondary focuser
the cam-filterwheel-MOAG-AO8-rotator and adaptor hell, took up 8.2" of back focus, no spacers, and the optimum BFD is 8.0", so im over already.
If I had to add a prime focuser, id be stuffed.
I havent got it all working yet, I got the rotator-MOAG-adaptor farm today, it just cant be that easy can it, oh no

.
Im posting a pic now, because if being 0.2" away from the BFD is no good, the whole lot goes in the bin
