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.
Want to learn how to make your own color composites of Cassini images? Check out my space imaging tutorials. I also recently wrote a much more detailed post on the challenge of making color composites from Cassini images of multiple moons.
