ATM Need some suggestions on a figure...

["AstroJack" <AstroJack@AVATM.com>]

Hi All,

I have been working on a 9.75" mirror that is approx. f/6.1.  The ronchi
images now are quite interesting and I know what I have, Just not sure which
way to go from here. Inside of RoC image is like this:
http://www.phil.uu.nl/~gjv/atm/ronchi04.jpg  With the curves  at the end of
the lines being quite a bit more severe.  On the outside this is what I
have: http://www.phil.uu.nl/~gjv/atm/ronchi03.jpg  The curved parts of the
outside of the mirror here show again much more severe curvature.  This
suggests a profile like this of the mirror:
http://www.phil.uu.nl/~gjv/atm/surf-D.jpg .  I currently have two laps, an
8" lap and a 5" Star lap.

I am tempted to attack the outside and try to drop it down some.  Or perhaps
I should just keep going CoC with about 1/2" of overhang...  Any thoughts
would be apreciated.  If nothing else this baby is WELL polished  out.

Thanks,

Jack Day
