The "F-Ring", sinking in the shadows... (elab. Lunexit)

Caption NASA:"The strands of Saturn's F-Ring disappear into the darkness of the Planet's shadow.
Background stars make trails across the sky during the long exposure. This view looks toward the unlit side of the Rings from about 55° above the Ring-Plane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Jan. 3, 2007 at a distance of approx. 1,4 MKM (such as about 900.000 miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 108°.
Image scale is roughly 8 Km (about 5 miles) per pixel".
