There are some gorgeous crescent saturn images coming down in the raws at the moment.

You can really see how oblate saturn is.
nprev
Yep...some lucky tourists will pay the big bucks to see that in person around the year 2300 or so... smile.gif

The oblation is what struck me, too.

What are we seeing in the images that alternate with with crescent shots? I assume it's the cloud tops, and the black band at the bottom is the shadow of the rings or the rings themselves.

Definitely.

Meanwhile, we'll have to be grateful for whoever at JPL takes the trouble to post the feeds.
jsheff
Yes, whoever does that is an unsung hero.

Notice the tiny black dot in the upper left of the crescent? In a similar image released last week
Ciclops such a dot was identified as Epimetheus. I wonder if that's what it is here or perhaps another satellite?

What is that little white dot at the bottom of the image?

If you turn the brightness up you can see that it's actually the rings intersecting the disc, not a moon.

EDIT: A shot that does show a moon, Titan alonside Saturn's right limb.

The bottom of the image was unfortunately clipped off on the spacecraft during readout.

Exquisite image.

It's interesting though how much 'noise' there is in the image, it appears they have barely 50% of the frame to work with...see attached image of W00016082 with the gamma correction turned way up. Do they use a mask of some sort to clean the lens smears and such?

even more stunning raws

can someone please stitch these so we can have the entire crescent
djellison
Two stitches..
paxdan
Thanks Doug, is that the e-ring showing up in the first?

Umm, i think something might have gone a little wrong with the second. i was thinking more like stiching this and this image.
djellison
That would be a blue image on the left and a methane band ( I think ) filter on the right. I did try the methane band images, but they have been 2x2 downsampled sad.gif

Quick and very dirty

Ah - you mean like this.

Pity the more exotic filters are down-sampled - but hey - we get what we get smile.gif

Below my personal attempt to process the two wide-angle crescent images W00016128 and W00016686 (for the last one, in reality, i used RGB images W00016687/8/9 and I made also an enhanced color version):

A dirty wide angle RGB mosaic from near the ring plane (groan, again!) with a moon I can't quite identify. Might be Rhea judging by the size, I dunno.

Nice mosaic!

Even though we are in a more inclined orbit, we do cross the ring plane twice an orbit wink.gif

there were some nice ring images taken last time I checked the raw images...

Saturn images are not my responsibility. I take no responsibility for any problems (or fantastic backlit mosaics) that might be associated with Saturn.

Are my eyes playing tricks on me, or do some of those clouds have discernible shadows, suggesting that they're projecting a considerable height above a lower cloud layer?
dilo
Absolutely yes, David.
Look to this old press release and see also previous post on the argument.

Saturn has a very "deep" atmosphere. The cloud-level gravity is actually only slightly greater than Earth's, and at cloud depths, the temperature is comparable to that of Earth's cloud levels. But Saturn has the lowest molecular weight atmosphere of any in the solar system -- almost pure H2. Simply put, that gives Saturn about 7 times the scale height of Earth, so cloud phenomena get some tremendous vertical stretching.

A rather colorful north polar area on Saturn is revealed in these WAC RGB composites. The unlit rings are too dim to be visible here without severe compression artifacts.

Colorization is, in reality, a sort of false color coding from original B/W.

(There are also nice G-ring pictures)

Yay! That's the Saturn shot I've been waiting for since I saw the plans for the tour and noticed the high inclination orbits. Too bad the raws are so saturated -- hope the actual data shows more subtlety in Saturn's disk.

Emily - there's quite a bit of detail in the region of Saturn's terminator, especially near the North pole where there are several bands and lots of clouds visible.

So far so good...
