Repair to Skywatcher finderscope
in Getting Started Equipment Help and Advice
Posted
Hi
I have a Skywatcher Newtonian telescope ( D:200, f:1000) The other day I noticed that the 'O' ring which was attached to the finder scope had broken. After a bit of digging around, I obtained what I believe is the correct size replacement ( 1.5 mm thickness, 52mm internal diameter). However, I can't see how it attaches to the finder scope ! Can anyone offer some guidance ? Many thanks in advance.
