Re: Machine Figuring John A's 16 inch with help from James Mulherin
- We have 160 nm to go so I think this is a safe move.

I called this morning but the machine answered again. I'm sure it must
be like Santa's elves on Christmas eve there what with your robotic
scope deadline moved up. I will call after the 14th as I would
definitely like to chat and thank you formally.
I would love to see a pic of this scope being lowered into the dome so
I could show my wife and tell her how lucky she is that my scope won't
be quite that large.
I've uploaded the surface error graph and it is right near the 100 nm
mark. But the edge looks funky in the graph not the ronchi. Perhaps I
could lower the whole surface with the center and edge correction runs
and bring everything up on the graph to achieve a smoother shape to it?
Hope All Is Going Well On Your End, John
- Thanks Richard.
