Re: [ATM] 7 inch spherical mirror

["Bob May" <rmay@nethere.com>]

Sheesh!!!  Now he tells me!  Been contemplating doing another
corrector plate try for my 6"F1.95 sphere that I have.  Think
that the better idea would be to put some of the correction on
the mirror and some on the corrector afterwords.
I'be broken two plates already trying to get this done.  The
first broke sometime in the night but the second broke while I
was present in the bathroom where I do my work at home.  An
interesting little tink that came out of nowhere.  Guess that
when you see bubbles coming out of the water underneath at a
fairly rapid ratee, you have too much vacuum!
