Saturn - November 6th

[James Willinghan]

Finished this image of Saturn from last Thursday night. That night a very rare occurrence that can only happen when the rings are seen edge-on from Earth was in progress. Titan was just over the midpoint of a transit of Saturn. The conditions started out below average, but settled  to around average so I was able to get about five sets of RGB data before some clouds came through and Titan was finishing its transit. I ended up taking the sets of decent data and played with derotating them in Winjupos (something I have not fooled with in a couple of years) and got a decent result. Titan is the larger dark spot on the right, Titan is dark because it has darker clouds vs than the icy surfaces of the Galilean satellites (except for Callisto). The other small black dot to the right is the shadow of the moon Rhea. Rhea was at center and too close to the rings and I did not pick it up. The moon Dione was near the tip of the right ring, but it also did not show. The other moons to the left are (left to right) Tethys and Enceladus.

I don't see a small black dot to the right, but I believe the one to the left is Tittans shadow.

My apologies all. The other small black do which is the Moon Rhea's shadow is to the left above the rings (sorry). Titan is the large black dot just above the rings on the left. It is dark and looks like a shadow, but it is the moon Titan. It is dark due to the darker clouds on Titan. The other Galilean satellites are icy and appear bright except for Calliston which has darker area on it.
