I was thinking about a threaded adjustment however it is a lot more work to make and you still need a way of locking it in place so I'm swaying towards a simple sliding mechanism with two grub screws. I want the MPCC and the spacer to insert into the focuser draw tube so the whole thing has to be max 50.7 OD and cant have anything sticking out.
I'll leave a fixed collar near the QHY8 end as a stop against the end of the draw tube. This gets around the problem with the recess in the MPCC causing tilt as the focuser locking ring will be around the spacer instead.
