Re: ATM Coulter 10.1 In. Mirror Quality

["AstroIdiot" <tgooch@arkwest.com>]

IHave a 13.1" of the same vintage, my mirror and most of the mirrors
of this vintage(as I understand) is slightly undercorrested and has 
some roughness. Set up a foucault test and check it. The glass is
certianly worth reusing, most just need polishing out and refiguring.
