Original caption:"The Cassini spacecraft views the far-off wispy canyons of Saturn's moon Dione and sees an interesting dichotomy between the bright wisps and the bright South Polar Region at the bottom. The view looks toward the trailing hemisphere on Dione. North is up.
The image was taken with the Cassini spacecraft's narrow-angle camera on Sept. 20, 2005, through a filter combination sensitive to polarized green light. The image was acquired at a distance of approx. 2,1 MKM (about 1,3 MMs) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 64°. Resolution in the original image was 12 Km per pixel. The image has been magnified by a factor of two to aid visibility".
Nota: un'immagine "modesta" di Dione, ripresa da una grande distanza e che - stranamente - evidenzia davvero molto bene la "profondità" dei rilievi Dioniani. Curioso, trattandosi di un frame NON 3D.
