Re: [ATM] Coulter Vs GSO mirrors

[William Marriott <bmarriott@pacbell.net>]

Hello;

So, I am not familiar with GSO optics, does someone
have a link to the manufacturers web site?

As  to the Coulter mirror, I know there was a
semi-recent 'new' Coultier  company, is the glass from
them, or the old, original. If from the original, I'd
use that, just because its a part of Telescope makeing
history, but Coulter's mirrors back then were known
for their wide variety of quality, some were really
great, others, may be best refigured.  

So, I have searched everywhere on the web, what was
Mr. Coulter's first name (Tom rings a bell, but I
don't think that is correct.)

More contemporary thinking people may be able to
advise you better.
