Hi Mario,
Great, the more the merrier. Attached, below, are the suggestions I
have received so far today. If you have any to add, I'd enjoy the
exchange.
Yes, I'm doing it all. Presently working on the 12" secondary mirror: a
convex hyperboloid made of fused quartz. Better a 32" under a dark sky
than a 40" under construction! I'll soon have a website up, which
follows the project's progress. First light will probably be ~18-24
months.
Good to hear from you. If you do attempt any of these listed below, I'd
be interested to hear your experiences.
Clear skies,
Tom
