Ooooh!.
I was brousing the last 500 "raw" images and spotted an overexposed F-ring shot with a trace of G-ring, so I contrast-stretched it to see more.. there was something in the foreground... Then I decided to contrast a badly auto-contrast stretched Saturn nightside image.

I presume it's not a gas atmosphere, but rather micrometer or smaller sized dust, down in the size range where it can be electrically charged by radiation or photoelectric effect, then moved out of the ring plane by magnetic field effects. That's what I believe is1 the explanation of the diffuse halo around Jupiter's rings.
And, Dilo, that did nicely improve the cosmetics of the images without blurring detail in the more adequately exposed parts. Nice. |

Another enhanced view (from last published raw img); here rings are almost edge-on and their inclination/position seems a little bit "odd"....
