Re: [ATM] Lens Wedge

["Bob May" <bobmay@nethere.com>]

The .008mm (about .003") sounds a lot more like what typical max.
wedge is for a design.
I played with a Newt. and put a .1deg. wedge in front of it.
Most of the error was coma (the light gets shifted off-axis) and
rotating the telescope to eliminate the coma got me a nice line
of spots.  Unfortunately, the program doesn't produce numbers but
you could see that the color error was of some significant
amount.

Replace the obvious words with the proper character.
