Mimas's "Eye": the "Herschel Crater"

Caption NASA originale:"Saturn's moon Mimas has many large craters, but its Herschel Crater dwarfs all the rest. This large crater 130 Km wide (80 miles) has a prominent central peak, seen here almost exactly on the terminator. This crater is the moon's most prominent feature, and the impact that formed it probably nearly destroyed Mimas. Mimas is 398 Km (247 miles) across. This image was taken with the Cassini spacecraft narrow angle camera on Jan. 16, 2005, at a distance of approximately 213.000 Km (132.000 miles) from Mimas and at a phase angle of 84°. Resolution in the original image was about 1,3 Km (0,8 mi.s) per pixel. A combination of spectral filters sensitive to ultraviolet and polarized light was used to obtain this view. Contrast was enhanced and the image was magnified by a factor of two to aid visibility".
