[ATM] 18-20 inch glass blank

[William Marriott <bmarriott@pacbell.net>]

Hello

Hello, gree?ıngs from N. Calif. Gonna be hot
?oday, but, probably good seeing tonite. 

Friday nite we had a small star party in my back yard,
and I had the privildge of looking through a really
nice 16 inch dob, with decent seeing for a little
while, and it emphasized how my 10in scope is nice,
but....

So, time has come to start hunting down the perfect
blank, only not sure yet what that is.  I know to keep
weight down I have to decide between a thin blank 
(1.5in?) and some kind of cellular design. 

In the world of cellular mirrors, what are my options
as far as who is producing such mirror blanks? I know
there is always Hextech, but a bit price-y, Newport
makes them, has anyone bought one from them?  I also
know that a couple of people on this list may be
involed with this technology. 

Any directions to appropriate webpages dealing with
this kind of mirror blank would be greatly
appreciated.

Oh boy!
