What are we seeing in the images that alternate with with crescent shots? I assume it's the cloud tops, and the black band at the bottom is the shadow of the rings or the rings themselves. -------------------- www.ridingwithrobots.org

Definitely. Meanwhile, we'll have to be grateful for whoever at JPL takes the trouble to post the feeds. -------------------- www.ridingwithrobots.org

In a similar image released last week Ciclops such a dot was identified as Epimetheus. I wonder if that's what it is here or perhaps another satellite?

I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853

If you turn the brightness up you can see that it's actually the rings intersecting the disc, not a moon. EDIT: A shot that does show a moon, Titan alonside Saturn's right limb. http://saturn.jpl.nasa.gov/multimedia/imag...eiImageID=79245 The bottom of the image was unfortunately clipped off on the spacecraft during readout. -------------------- www.flickr.com/photos/ugordan

You can really see how oblate saturn is.

Exquisite image.

It's interesting though how much 'noise' there is in the image, it appears they have barely 50% of the frame to work with...see attached image of W00016082 with the gamma correction turned way up. Do they use a mask of some sort to clean the lens smears and such?
