Some great hints in those postings. Thanks. There could be a decent article in there somewhere, Les.
I too dread the prospect of having to disassemble and clean my primary mirror. Although I have read that using distilled water is the way to go I have wondered if filtered rain water might be just as good. Then there is the cleaning itself; how is it done? Does one rinse the thing and hope for the best? If not, then what should be used to swab the mirror?
The mere thought of scouring it in some manner or other makes me go weak in the knees. Right, I'm off for a bit of a lie down.
