Quote:I try to never do any maintenance on my scope - including collimation - unless the tube is horizontal But that isn't always possible, and I've had a few "D'Oh"! moments myself.
Quote: ...and it all went downhill from there
Quote:I got bummed out when I was removing my finder bracket and dropped one of the teeny tiny nuts holding the bracket. I could hear it bouncing around on the mirror. Perhaps not surprisingly there was absolutely no visible damage at all. But I still had a coronary when it happened.
Quote:Wow OK. Blacken the dings but be careful here. You don't want a reaction with the paint versus coatings and this foggy apron of fog around the paint. My knee jerk thing said use a Sharpie its got acetone but mirrors sometimes are cleaned with acetone. I suggest staying well away from lacquers and outgassing enamels.Good luck. Sounds like the real damage here is to your Psyche and I'm sympathetic here but don't let it precede the benefit of what might be at least a good mirror.Pete
