Check out the new multispectral Dione series! Here is one of the frames:



Quite a lot of cracks!

The new Dione observations have been added to Steve Albers' excellent global mosaic at:

And here, in another example of the polar projection method, I have cropped the bottom half of his map (in the spirit of open source image processing we are all enjoying... hope that's OK, Steve!) and used Photoshop's filter>distort>polar coordinates method to make a map of the southern hemisphere centered on the pole. This is what a cartographer would call an azimuthal equidistant projection (and the spherize tool could turn it into an equal area projection).

See the big basin... above it, across the data gap, we see the best Voyager image, and a group of ridges and crater chains long recognized in that area turn out to be radial to the basin. An ejecta lobe and basin secondaries, most likely.
