Hi all,
I've made an RGB image of an outer region of the hercules supercluster.

(19000x19000 pixels, 24MB)

(9000x10000 pixels, 6MB)

It's the outer region, but it's oh so crowded with galaxies :-)
I have not made pixel-downgraded versions: the resolution of the image
is too good :-) The seeing is 0.7 arcsec in all three bands.
Unfortunately mosaicing is visible in this coadd (more or less
depending on your monitor), I'm now working on better coadds with
better background subtraction.

Jeffrey
