Hello all,
I have a 16" lightbridge and it has developed a light fog of small (say 0.5mm) grey, transparent spots
. I cleanedthe mirror with detergent and demineralised H2O but it did not remove them. Rubbing firmly on a sliver at the edge does nothing also. The scope is 5 weeks old and has had condensation over it a couple of times. Is this a normal part of oxidation or is there somethig more sinister happening? The pics show it in the worst possible light while looking straight down the barrel with no torch on it hardly shows them.
