Tip for Eyepiece Caps

We all know how easy it is to loose black eyepiece and finderscope caps in the dark. I bought a package of self-adhesive reinforcement rings (they're designed to keep loose-leaf pages from tearing free of binder rings)at an office supply store. I stick one to the inside and one to the outside of each cap so they are easier to find in the dark either with the naked eye (preferred) or with a flashlight (be mindful of others' night vision with any white light).

Like it! It's a Hints from Heloise type tip!

Having lost caps before, especially off of finders, sometimes off eyepieces, this could help. Perhaps there are even some flourescent, glow in the dark sticky things, too!
