I was struck by how much images like this...
http://saturn.jpl.nasa.gov/multimedia/imag...5/N00148493.jpg ... remind me of the view through my 4.5" scope when I peer into it without the eyepiece. LOts of fascinating internal light reflections there... -------------------- |

Going by information elsewhere on the forum, Cassini passes the following moons at reasonably close distances on 27th January. I have no information as to whether the moons are in eclipse at closest approach, whether imaging is planned, or whether other science activities/downlinks take preference at the time. Pixel values assume imaging bang-on closest approach. I would imagine Dione and Prometheus will be imaged, but smaller 'rocks' probably doubtful.
Pan: 95,233km - 54 pixels in the NAC at closest approach Prometheus - 30,492km - 546 pixels Aegaeon - 13,305km - 6 pixels Methone - 74,527km - 7 pixels Telesto - 95,643 - 42 pixels Dione - 46,805km - more than 1 NAC frame Jase |
