(ATMoB:Discuss) Refractor Objective retaining ring tool
Do we have up at the clubhouse a tool to remove the retaining ring on refractor objectives? I need to loosen mine on my 4" because I am getting traingle diffraction rings and was told the retaining ring was too tight.
Any information would be helpful.
