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.

Ugordan:

I know all about the scattered light problems. It definately doesn't help. but you can see the nightside of Janus and the other small moon <Epimetheus? Prometheus?> in silhouette against the glow as *darker* than the background. That portion of any glow MUST be behind the moon, not in the camera.
