Greetings All,

Thought I'd share a little something with you all,

http://lerch.no-ip.com/atm/zoc10.gif (970KB animation)

If you can see thru the image aberrations and distortions, sure looks to me
like the Star test simulation is working mighty fine :)

If your curious, the original image came from Jon Bent's website (with
permissions) from here:

http://home.no.net/jonbent/Startest.html

The star test simulations were based on Foucault data provided with Jon's
mirror, using an 18% obstruction and 8 waves defocus (PS, I made a small
internal change to the Gamma function inside FigureXP (0.89 gamma to 0.91
gamma) I haven't rolled this change out yet, so existing beta versions
won't look exactly like our animation, but should be dang close!)

If you want to play with the data, here's a copy:

So, what do you guys think?  Are we onto something?

Take Care,
James Lerch
