The problem, of course, is that everything in the Saturn system is in motion, including Cassini, and time passes between each of the three filtered images used to make this observation. Cassini's pointed at Rhea, keeping it in the center of the frame, but in the meantime, Cassini's perspective is shifting, causing the rings and moons to appear to move. Sometimes, you can pretend this isn't happening for the rings and you get decent color results. But there happens to be a dark gap in the rings right behind Rhea, which is visually interesting, but which causes issues with the alignment of the color channels.

Ci vuole raccontare che il buffer del computer di bordo della cassini non ha lo spazio per contenere uno scatto in R,G,B e le 3 foto devono essere fatte a distanza di ore oppure trimestri l’una dall’altra?!

da non confondere con la sfigata sonda galileo:
