Hi all,
I am ready to start parabolizing my 16.5" mirror but first I want to
determine exactly where I am.  I didn't use the ronchi test with my
10" so I am still learning how to interpret problems shown with the
Ronchi. The link below shows a current pic of the ronchi test on my mirror.
 Any evaluation would be appreciated. Also any web links with information
concerning problems and how the Ronchi test shows them would be helpful. 
The archives have lots of references but most of the associated links are
dead.
