Hi all,
Please bear with me. I have posted several more Ronchigrams to my web site.
There is a number at the bottom right of each pic that matches the numbered
paragraphs. I would appreciate comments.

I am using a 10" subdiameter tool.  Working exclusively TOT.  Mirror
is F4.6.  16.5" x 3/4"

Clear skies, Jerry

BTW - Would it be easier to continue on to a parabola rather than try to
get back to a sphere first.  The mirror appears to be heading that way.
