Odysseus: the "eye" of Tethys

Caption NASA originale:"Saturn's moon Tethys turns like a great eye as the enormous crater Odysseus (450 Km across) rotates into Cassini's view. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 6, 2005, at a distance of approximately 1,7 MKM (approx. 1,1 MMs) from Tethys and from a Sun-Tethys-spacecraft, or phase, angle of 35°. The image scale is 10 Km (approx. 6 miles) per pixel. The image has been magnified by a factor of two and contrast- enhanced to aid visibility".
