[ATM] 24" mirror finished

[Bob May]

The secondary is going to be calling for some star work.  Get it
roughed out to approximtely the right ROC and put some kind of
shape on it.  Having a test plate with the correct shape on it
will help in making the proper shape for the secondary and star
testing will finish it up nicely.
It will help if the primary has a nice smooth shape according to
a Ronch Grating.
