Saturn and moons

21:24 12/12/2004 UTC

This is a dual exposure of Saturn and its moons. Moons are exposed with higher gain to bring the fainter moons out, but overexpose Saturn. Another exposure with less gain was taken to mask the overexposed planet with correctly exposed one. Four moons are visible in the image. From the left they are: Titan, Rhea, Tethys and Dione.
