My MPCC has the indented recess around the barrel, and my Moonlite's brass compression ring kind of slips into it but I think it's causing my camera to not sit flat on. I'd prefer to have the focuser pushed fully flat onto the MPCC flange. To do that I need to fill in that recess.
I noticed a
thread here where erick used some carbon fibre adhesive sheet wrapped around. Looked like expensive option. Would any tape do? Electrical tape? Any other ideas? I just want a smooth barrel into the focuser.
