Hi all,
Just a short progress report. I took my first set of Foucault readings
today. Just to get an idea of what my mirror is doing that I can't get from
Ronchi.

1- .034"
2- .034"
3- .044"
4- .059"
5- .088"
6- .146"
7- .261"
8- .301"

Ronchi showed me that the center was still too spherical, but I could not
tell what zones 6-8 were doing. I just knew they were more corrected than
the center, but over corrected compared to the center.  From these numbers
I can tell that zones 1-5 are under corrected and zones 6 through 8 are
nearly perfect.  From here I know which way to jump. Thanks to all,
Clear skies, Jerry
