Simple Battery saver for ye olde Celestron 8x50 Polar Finder
Description
I keep forgetting to unscrew and shut off the the reticle illuminator led. After the third battery set in a week here the solution. The red open ring clicks around the illuminator screw and keeps it shut off. A simple look at the finder and you know for sure whether it is draining battery. So simple, so stupid, so effective!
