Here's a cool global map of Saturn's moon Iapetus, stitched together from the various Cassini flybys. Cassini didn't see the entire moon, so the imaging team put in photographs from Voyager to cover the missing polar regions.
You can see its distinct equatorial ridge on the left-hand side of the image, and the mottled dark and light patches that give the moon its Yin-Yang look. The image scale is 803 km per pixel.
It's a little old, but check out
