Re: [ATM] my ota Design for mounting an autocollimation flat?

[Guy Brandenburg <gfbrandenburg@yahoo.com>]

Inspired by what I saw a couple of summers ago at
Stellafane, I want to do the same thing. I also have a
fairly large flat. But I've been a bit too chicken to
actually start making the mountings. Anybody know how
the folks at Stellafane in 2003(? I think) had theirs
mounted?
