NAC RGB ring scan of the left ring ansa, unlit side, 2010-01-23:

Very nice! As if the bright F and C rings and Cassini Division weren't enough of a clue, this observation was taken at high phase over the "unlit" side of the rings. I put unlit in quotes as there is obviously some contribution from Saturn shine as well.
Wow, very beautiful!
Image from [EDIT: UN]lit side of rings. Movement of a sheparding moon and ringlet chunks can be seen as multicolored splots in the lower right part of the image:

I think that is still the unlit side I do believe...
nice The moving parts really jump out in such a composite.
What the.... ? Does Aegaeon (btw, is it spelled that way or Aegeaon as in Looking Ahead?) really look like a stick or is that motion smear?

Sure looks like the former case based on all the raw images. Is this a high phase shot?
No it's Aegaeon, I just spelled it wrong... Noticed that last night...
The phase angle is around 75 deg.
At 75 degrees phase angle, did we just discover the most elongated object ever imaged so far?
Here's an animation that runs through 17 of the 18 Aegaeon NAC shots (skipping the second one, in which I just couldn't find it). Flickering is caused by Cassini using different exposures & different filters. It's enlarged 2x.
Atlas is definitely thin, but this one appears to outdo it, assuming we didn't by chance get aligned at Aegaeon's equator. Tantalizing. I'd love to see a RGB color composite and compare it to other small rocks, I'd guess this one will turn out to be bluish as well.
Best I can do with Aegaeon - images from the start and end of the sequence. Each is a composite of about 6 or 7 frames, omitting the invisible or saturated frames, enlarged to 400%.

Dione. Mosaic of four images. Severely warped, tweaked, cajoled, and finally beaten into submission to account for spacecraft motion:

At full resolution, at least 8 ring spokes can be seen in the B-ring.
Mike - I wasn't impressed, then I clicked "full resolution" - wow!
I like the fact that you didn't correct the RGB separation of that little moon (must be Prometheus, I guess) near the ansa. Sometimes it's nice to leave that stuff in, and then let people ask why it looks like that -- it gives you an opportunity to explain the way color imaging works.
Agreed, coolness on the number of spokes!
Only three frames for this? What I was just looking at is only the rings and no Saturn.
I see the nightside of Saturn illuminated by the rings...

A couple more Prometheus images got posted from the Jan 27th flyby.
Here's an RGB composite of when it's crescent was thinnest.

A rework of an earlier mosaic that I did for another purpose and thought I'd link to it here.
It is a graphic that annotates and compares the Saturn Ring raw image mosaic of January 27, 2010 to PIA08389 (unlit side of rings mosaic). The Cassini raw image mosaic is enlarged 2x. Kinda cool to see how the brightness of the B-ring seems to vary around the ring - a phase angle backscatter thing?
