In the darkness

Sunlight filters through Saturn's Rings in sepia tones in this artful view from the Cassini spacecraft of the dark side of the Rings. Those rays from the Sun directly reflected from the lit side of the Rings onto the Planet strike and illuminate the night-side Southern Hemisphere.
The densely populated B-Ring blocks much of the Sun's light and thus looks quite dark and Tethys is a mere sliver below left.
Note that unprocessed wide-angle camera images taken in a high-phase viewing geometry generally contain stray light artifacts. These have largely been removed from this image by computer image processing.

Cassini was about 3° above the Ring-Plane when this image was obtained on Sept. 6, 2006. Images taken using red, green and blue spectral filters were combined to create this natural color view. The images were taken using the Cassini spacecraft wide-angle camera at a distance of approx. 1,8 MKM (about 1,1 MMs) from Saturn and at a phase angle of 154°. Image scale is roughly 106 Km/pixel.
