This natural colour view of 14 December 2004 shows the moon Dione which has strong variations in brightness across its surface, but a remarkable lack of colour, compared to the warm hues of Saturn's atmosphere.
The images used to create this view were obtained with the Cassini-Huygens wide-angle camera at a distance of approximately 603 000 kilometres from Dione through a filter sensitive to wavelengths of ultraviolet light centred at 338 nanometers. The image scale is about 32 kilometres per pixel.
