I have a new C3 260000 pro with a Moravian 9 position filter wheel.
Anyone know the back focus for this combo?
From the manual it should be 47.5 mm or 41 mm (depending I guess on the M68 adapter?) but I need confirmation from other users.
The reason I ask is because I have some star elongation that it’s harder to diagnose.
I eliminated tilt in the imaging train by using only threaded connections, so I need to know the back focus is not the issue.
My imaging train consists of a FT 3.5 focuser, extender, field flattner, extender, FW, camera. All threaded connections
