Cassini goodies: Telesto, Janus, Prometheus, Pandora, F ring
As I mentioned yesterday, the Cassini raw images website has been full of goodies lately. Here's a sample.
(First, a quick update on the Station fire: Mount Wilson is still unscathed, and firefighters predict today will be a better day. Concern is abating.)
My favorite recent set of images was targeted at Janus. Take a look at this animation and see if you can figure out what's going on before you read any further:

Telesto
Cassini captured this view of the leading hemisphere of Telesto on August 27, 2009. Telesto is a small moon, 34 x 28 x 36 kilometers in diameter, that occupies a Lagrange point behind Tethys in its orbit around Saturn. This is an approximately natural color view composed of raw images.
