The "Eye of Mimas": Herschel Crater

Caption NASA originale:"During its approach to Mimas on Aug. 2, 2005, the Cassini spacecraft narrow-angle camera obtained multi-spectral views of the moon from a range of 228.000 Km (about 142.500 miles).
This image is a narrow angle clear-filter image which was processed to enhance the contrast in brightness and sharpness of visible features.
Herschel Crater, a 140-kilometer-wide impact feature with a prominent central peak, is visible in the upper right of this image.
This image was obtained when the Cassini spacecraft was above 25° South, 134° West latitude and longitude. The Sun-Mimas-spacecraft angle was 45° and North is at the top".
