While using the Cassini PDS images to make a big cylindrical map of Saturn's southern hemisphere I decided to also process a few PDS images to make some mosaics and color composites as 'by-products'.

In September and October 2004 Cassini continuously observed Saturn for several weeks using eight different filters (CB1, MT1, CB2, MT2, CB3, MT3, BL1 and UV3). The result was a 2x2 image atmospheric movie and (needless to say) lots of interesting images. The images in this and the following posts are derived from a few of these images.

Unless otherwise noted all of the images I used for the color composites I'm posting here are from this sequence of images and were obtained from a distance of 7.2 million km on September 30, 2004.

Here is a 2x2 mosaic of the southern hemisphere:



The overall color is fairly accurate (possibly a bit too saturated), however, small scale features have been sharpened slightly. This image is composed from CB1, BL1 and synthetic green images based on the CB1 and BL1 images. Provided the synthetic green image is properly made the end result is almost indistinguishable from color composites where GRN images are available.
