TOA150 image train
Hi
I am setting up a TOA-150 for imaging and need some advice on the order of things. Using the TOA-67 flattener and a FLI focuser (either Atlas or PDF) should the focuser come before the flattener or after? Before looks a better option but probably means more adapters. After looks simpler but uses up some of the flattener back focus.
Any suggestions would be much appreciated.
Regards, Roger
