It's axiomatic that as soon as I post about pretty Cassini pictures, another set of pretty photos will appear on the raw images website. This one is part of a series showing Dione passing in front of Titan. I always enjoy the contrast in brightness and sharpness between any of the icy moons and Titan's dim, fuzzy blob.
