Caption NASA:"The Cassini spacecraft snapped this shot of cratered Dione as it flew by the Saturnian moon on Oct. 17, 2010. The large crater at the center of the image is Erulus, which is about 120 Km, or approx. 75 miles, across. This view looks toward the Southern Latitudes of the Leading Hemisphere of Dione.

The image was taken in Visible Light with the Cassini Spacecraft narrow-angle camera. The view was acquired at a distance of approximately 41.000 Km (such as about 25.000 miles) from Dione and at a Sun-Dione-Spacecraft, or Phase, Angle of 53°.
Image scale is roughly 240 meters (787 feet) per pixel".
