Hi Paul,

I don't know any of the measurements of your system and the proposed flattener but is there a way for a machinist to mount the flattener inside the focuser? That would recover, or share, some of the back focus. I did a similar thing when I was building a manual rotator and I mounted my WO flattener inside the rotator.
