Doubtless Aegaeon's imaging sequence on the next orbit has been designed to take account of that moon's orbital uncertainty. Add to that it's a very close, fairly fast flyby, of a moon that has a low albedo, and is tiny even compared to Atlas...

Yep, the observation is basically a series of two-frame mosaics. Should help to ensure that Aegaeon is in the FOV.

A contrast stretch shows even more grooves on Epimetheus than show up at first glance.

I've added artificial color to the WAC clear-filtered frame of Epimetheus, approximating the view a human might have from the same vantage point.

Has anybody else tried their hand at the Atlas images? Here are my quick-and-dirty versions, but I know others can do better.

Eli's had a crack at Atlas already, Emily:

This is my attempt at the Prometheus obs with a semi-automated method of removing the digital smuts:

Three-frame, clear-filtered stack of Atlas, enlarged by 250%. North is up.

Looking at the PDS data for this medium-range flyby of Atlas, I realized a number of frames at the start of the sequence were taken against the backdrop of Saturn's night-side. Thanks to the faint illumination of the cloud decks with ring-shine, an extreme contrast stretch of the images reveals the moon's equatorial bulge and southern hemisphere in profile.

At first I was really taken aback...Looks like Phobos 2 image from VSK in 1988
