How 'bout a scouring pad? Just kidding, but I think I may have damaged either my corrector plate or the mirror by cleaning with usual photo lens cleaner material, although I was extremely careful. But I think there's really something wrong with my optics now. Thanks, Joe
The next obvious question to me is, what it the right (careful) way to clean a newtonian mirror?
I have read somewhere that using a mild dish soap like Dawn is prefered. Any wiping or rubbing will grind dirt into the mirror. So how do you get the dirt off? How about using an old shaving brush (probably couldn't find one these days) or a photo air brush?
