ATM First Ronchi Test

[Mike Warne <mwarne@pihana.com>]

Hi,

I took a first look through my ronchi tester last night.  The mirror is 10
inch F5.5.  

Outside ROC the Center line is rather fat, wider in the center, and smaller
at the edges.  The  lines on either side of the middle line are curved. The
curve of the lines on the left of center generally folow the shape of the
left edge, likewise for the right.  The ends of the lines also have hooks
pointing away from the center of the mirror. 

So it appears I have at least 2 problems, The edge and something else --
does it sound like a raised central area?  


Any Suggestions?


Thanks,
Mike Warne.
