Here's a quick'n'dirty sequence of wide-angle frames acquired around Cassini's recent ring plane crossing. I've reduced the size to 50% to make the GIF more manageable, the full sized sequence is a tad over 5 megabytes.
![]() Cassini was moving north so the near side of the rings moves down here. Things to note in the movie: 1. the near side is noticeably brighter than the far side, likely due to saturnshine. 2. the Cassini gap becomes brighter at low inclinations, both the lit and unlit sides. 3. there's a quick, dark spoke at the beginning of the sequence visible. It's visible in the 2-4th frames There's a bit of static hot pixels I haven't removed yet. Not very visible in the reduced resolution but noticeable in the full resolution. There are also a few moons running around, either Mimas or Enceladus and perhaps Prometheus/Pandora. -------------------- |

Very nicely done! Thanks.
Daphnis looks like it is enlarging the Keeler Gap in its wake. |
