Four moons and a ring
amateur image processing,
Saturn's small moons,
On September 17, 2011 at about 1200 UTC, Cassini pointed at the mid-sized moon Dione and watched as it transited Titan while the rings and two small moons passed by. Pan is a tiny object orbiting within the A ring's Encke gap, while Pandora is the outer shepherd satellite of the F ring.
