So one of my friends from my Astronomy club has given me a 6in mirror blank at our club mtg last week. I'd like to try my hand at making my own mirror. I didn't have time to stay and ask questions ( dropped in to return an astronomy lecture vid to our library). How do i go about doing so? I'd like to eventually use it in a dobsonian, for photography purposes. turbo-1 i'm looking at you bud, been awhile since i posted here, how've you been?
