I don't know whether this has ever been reported in the forum.
During E18, in December 1998, Galileo took some camera calibration pictures of Saturn, Uranus and Neptune. This is one of the clearest views of Saturn (untreated "raw" image). However, I cannot make out Uranus and Neptune from their raw image. I think they are somewhere between the cosmic rays and radiation blemishes...

We discussed it at some point. I made a false color version of it.

Didn't you say that one's from C22? http://www.unmannedspaceflight.com/index.p...ost&p=13606
Is there more than one calibration observation of Saturn? -------------------- |

Since we're at the topic of unremarkable Saturn sets, here's one showing the state of Cassini's narrow-angle camera after the Jupiter encounter:
Gamma-correct display version. Titan is the speck at left and appears much more red because the haze scattered blue light strongly - hence a mostly bluish halo around Saturn. This is AFAIK the first ever image of Cassini's ultimate target, taken on July 13th, 2001. The phase angle is similar to what can be observed from Earth. As a comparison, an image taken 15 months later showing the haze is pretty much history:
