Seen approximately as it would to the human eye, this image of Saturn's moon Dione was taken on 11 October 2005 by the NASA/ESA/ASI Cassini spacecraft. Blue, green and infrared (centred at 752 nanometres) spectral filters were used to create this colour view. The images were obtained with the Cassini spacecraft wide-angle camera at a distance of approximately 39 000 kilometres from Dione. The image scale is about 2 kilometres per pixel.
