Was that for your 300mm, or for the shorter lenses?

The moire lines seem more predictably obtainable on the original target (with cross hairs) than with the concentric rings.
Yes, I did try to make the chance and amplitude of large area moiré as nasty as possible in the original.

In the later case the concentric rings resulting from moire seeem to dance over the screen and are, to me, less obvious.
Okay Herb, thanks for the feedback. It helps me to concentrate on the variations of the basic concept that are more likely to succeed.
