Re: [ATM] ritchey cretians

Hello Khail;

Hello

As 1/2 of the dual 20" fused silica Ritchey-Chrétien
consortium, I can tell you the best place to get info
is by searching the ATM list archives, as the topic
comes up here and there, as well as go to
Wellman-Bell's website, and order the great book,
Telescope Optics, Evaluation and Design, by  Harrie
Rutten & Martin A. M. Van Venrooij, get the software
that comes with it (added cost) and you will be at a
good starting place.

The all to often used, some will start, few will
finish  comes to mind.
