Re: ATM ultralight flexible mirror
>...an old drunked astronomer told me
Oh yea, well when I was an old drunken college student I made an 18" f/1 on
an irregular 1/16" inch piece of tempered window glass from the student
union building. And I had to grind it in a ditch, with a rusty nail, while
I was on my knees, and it was raining. I polished it with spit and a piece
of worn out blue jeans. The mirror was 1/100 wave, at least.
Saddly, it was later used as a punch bowl, got a little scratch at the
center, and I threw it away. That's why I don't have it anymore.

PS I remember the party. I remember the ditch. It might have been a 20"
