>Can someone provide Foucault and Ronchi images of this astigmatic mirror?

Jerry,

I have archived 120+ unmasked Foucault images on mirror C, here:

http://lerch.no-ip.com/atm/MRR/

Click on Mirror C Results at the top, Section #3, sub-section 3 (Between the 
robo Foucault results and the interferometry results)

BTW, each image is flawed by a small speck of dust some where in my CCD camera. 
The flaw shows up as a small 'blotch' in the bottom center of each image.

Hopes this helps.

Take Care,
James Lerch
