Cassini photographs Saturn and moon

A wonderful raw image from the Cassini spacecraft showing a crescent-lit Saturn and one of its 61 known moons.

Honestly I’m not sure which moon this is. Could be Tethys, could be Titan, it’s hard to make out in this wide-angle view. Also in crescent, its night side is dimly lit by reflected “Saturnshine”.

Cassini has been busy taking detailed photos of the rings, now lit edge-on during the planet’s equinox, but has managed to get some nice wide views like this as well.
