Rings and Moons (detail - x4 mgnf)

Caption NASA originale:"This image captures several important targets of the Cassini mission: icy moons, rings and the gaps in the rings that may contain small undiscovered moons. Mimas (398 Km across) is easily seen near lower right. Epimetheus (116 Km across) is visible left of center. The 4.800 Km wide Cassini division is the dark swath at upper left. The Encke Gap (325 Km wide) is visible as a dark curve near the edge of the A-Ring. The thin F-Ring is seen here, exterior to the main rings.
The image was taken in visible light with the Cassini spacecraft narrow angle camera on Sept. 10, 2004, at a distance of 8.9 MKm(5.5 million miles) from Mimas and at a Sun-Mimas-spacecraft (or "phase") angle of 84°. The image scale is 53 Km per pixel.
The image was magnified by a factor of four to aid visibility".
