  Cassini sights the far-off wispy canyons of Dione, and reveals an interesting dichotomy between the bright wisps and the bright south polar region at bottom.

The view looks toward the trailing hemisphere on Dione (1,123 kilometers, 698 miles across). North on the moon is up.

The image was taken with the narrow angle camera on Sept. 20, 2005, through a filter combination sensitive to polarized green light. The image was acquired from a distance of approximately 2.1 million kilometers (1.3 million miles) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 64 degrees. Resolution in the original image was 12 kilometers (8 miles) per pixel. The image has been magnified by a factor of two to aid visibility.

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.
