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

It should be OTA, FLI Focuser then flattener. Focusing is achieved by moving the whole focus, not the distance between flattener and CCD which should remain the same

Hi Colin
Thanks for confirming that, it did appear like the most sensible option.
