  Saturn's nearly edge-on rings are caught between two moons.

The edge of the F ring has a blurred appearance with bright Dione (1,123 kilometers, 698 miles across) as a backdrop. Oblong Pandora (81 kilometers, 50 miles across) transits Dione and heads off toward right.

This view looks toward the unilluminated side of the rings from less than a degree above the ringplane.

The image was taken in visible green light with the Cassini spacecraft narrow-angle camera on July 24, 2007. The view was acquired at a distance of approximately 2.2 million kilometers (1.4 million miles) from Dione at an image scale of about 13 kilometers (8 miles) per pixel.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA's Science Mission Directorate, Washington, D.C. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.
