This does not look like Moir? to me, but like "banding".
This could be due to over-compression, but it may
also have something to do with the way you
correct for chromatic aberration and for the
vignetting of the original images.
I was using a Photoshop action to correct for
these things, but then I started to import my
Nikon D70 fisheye images into Photoshop using the
"Camera Raw" filter. I found that it gives me
very good control over Chromatic aberration
(colour fringing) and over the vignetting (light
fall-off) with very little or no visible banding
in the sky areas.
One example of this is at http://www.uricogan.com/qtvr/ferry.html
And.. by the way, my submission to "Marketplace"
is at
