Best thing to do is to get a Ronchi grating and put it near the
focus of the scope.  This will show any turned edge real fast!
The lines should be straight with a star image.  Any wandering of
the lines from seeing conditions will also show up very nicely.
All results of the Ronchi grating will be identical to that of a
spherical mirror on the bench at the ROC.

Replace the obvious words with the proper character.
