[AZ-Observing] Re: Good Seeing, Saturn's Colors, and the Jovian Moons

Tom,

Is that the Encke *Division* I see on the right ansae? The feature is
quite
near the edge of the A ring and in the right place. On the other side,
the
contrast feature looks more like a minima and is closer to the center of
the ring. What does everyone think? Am I seeing things (as usual)?

BTW, great image, you have me wanting a Webcam . . . .

Matt

Most of what you see in that image was apparent visually on Saturn.  We
spent a lot of time working on the color balance.  We find that many of
the
images present Saturn in stretched colors.  Since we spent as much time
observing Saturn as we did imaging it, the true colors were fresh in our
minds.  Saturn's colors are mostly shades of yellow through brown.  The
A
ring is gray, and the B ring is a brighter yellow than the globe.  And
the
C ring is only slightly brighter than the surrounding sky.
