(continued from previous post)



I'll post a color image soon, if someone else doesn't beat me to it.

Pandora is a very strange place, indeed.

Here's color (IR3, UV3, P0+GRN; top left), as well as a 3d anaglyph (top right) and a cross-eyed stereo pair (bottom).

Is it just me, or do most of the craters on Pandora seem to be in advanced states of erosional degradation?

Also, there is a highly interesting pattern of radial spokes within the crater roughly midway between "top" and "bottom" in thiese images, about a quarter of the width of the images to the right of the terminator.

Probably not erosion. I suspect that dust from the F-ring has mantled the surface, giving it an overall muted appearance, by shallowing smaller craters and covering over the smallest craters.

um3k, I had same idea about producing false color (IR3, UV3, GRN) image, then an enhanced color version (lot of work to minimize cosmic rays tracks):

Very cool! I've made a super-res image, I'll upload it soon. It is made of three images, I can't do more than that due to motion issues. I didn't do much cosmic ray removal, either. But it's still pretty decent. wink.gif

Nice work! I can't wait to see what that will do when we have raw data to use!

Interesting!... is it possible to remove jpeg artifacts in order to better see details?

um3k's super-res pic is very nice... I hadn't noticed the set of grooves near the terminator before (I'm only geting very brief glimpses of things). I'm very fond of grooves.

Finally, thanks to um3k animantion, I was able to do make 3D Pandora images:
anaglyph:

Imperfections are due to slight illumination change...
