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... -------------------- |

Here's a hint of what's hiding in the shadows... Aha! I KNEW it! Saturn's small moons are covered in jpeg compression artifacts! -------------------- If Occam had heard my theory, things would be very different now.

A cleaned-up view of the end facing the F ring. There's a hint of lineations near the bottom, and a smooth area in the middle. I expected a smoother surface.

Here's an animation consisting of six NAC frames that show the shadow of the F-ring moving across Prometheus. Some spacecraft movement is evident too.

Some spacecraft movement is evident too. That wasn't 'spacecraft movement', that was the shock wave from my jaw hitting the floor. Every time I think "That's one of the coolest things I've seen on UMSF!" someone posts something like that...! The wonders we're seeing... just incredible... -------------------- |

That's not Prometheus, that's a beating heart

Color composition from images N00150201/202/203 (respectively clean, Red and Blue filters); on the right weak illumination is enhanced.

I need a new word, Awesome just doesn't cut it anymore. Out of curiosity have there been any other examples of ring shadows on Moons captured before?

Tremendous. And yes ring shadows have been seen on moons before, both by Cassini and Voyager.

Yay! Glad to be getting really good views of Prometheus finally. It seems to be the last of the bigger rocks that needed it.
The Aegaeon images definitely seem to show some shape. Elongated, but then again they all are. http://saturn.jpl.nasa.gov/photos/raw/rawi...?imageID=211946 (Edit: D'oh, I see now that Aegaeon's been discussed in the Cassini Raws thread already.) |

An "extended color" composition from N00150212+214+215 (filters G, IR3 and UV respectively).
Ring shadow colors are probably a timing artifact... -------------------- I always think before posting! - Marco -
