Getting more and more into this awesome field and as such getting better equipment, and want to keep that new gear look.
My question is regarding eyepiece retention and the marks it leaves on the eyepieces.
I know some focusers use collar/collet style retention systems, but I only have a 2 screw retention screw that marks my current EPs pretty heavily (A skywatcher 130p). Also, thinking a repurposed feeler gauge as a physical barrier between the two surfaces, but my issue is with the efficacy and if it would actually fit with an EP in there.
Are there any tips and
