Re: ATM Kennedy Optics vs Galaxy Optics

John, did you get a hyperbolic mirror also?  I had one guy in my class that
had a 10" that he was just not happy with.  I got him to finish up a plate
glass mirror that was about 1/20th wave and almost the exact same distance
from the back of the mirror to the focal plane (think about why that one for
a moment).  He is now very happy with his telescope and in addition, while
working on the mirror, he kept putting it in his scope and doing start tests
with it.  He said that even at a half wave accuracy with a bad turned edge,
the images were better than the other mirror.
