Re: [ATM] TDE (That Darned Edge)

The TDE is not too bad but there is still a bit to go.  It is a
bit difficult to really get a good handle on the amount due to
the fuzzy image.
In the future, please crop the image so that the mirror fills the
image as this makes for a faster load to us slower internet
accessers.  Also, Ronchi images don't need to be that large to
see the lines.  Please focus the camera on the mirror and when
putting a light behind the grating, mask off most of the lines so
that there is only 1 or a few slits that the light gets through.
This sharpens the lines very nicely and doesn't reduce the amount
of light by any significant amount to the camera.
