Fantastic! Thank you Pablo.

I wonder, could you tell us whether the protrusion at the bottom of the image is the central peak of the large south-polar basin?

Bit late to the party, I know, but here's my take on the June 20th sequence:

The distant view from January essentially shows the same side of Helene, albeit illuminated from the opposite angle:

http://photojournal.jpl.nasa.gov/catalog/PIA12758

Now, the caption states that this is the trailing hemisphere, which I *think* is a mistake; the 'Eyes on the Solar System' simulation and the mini-atlas suggest that this is actually the leading hemisphere.

Here are two shots from the January and June flybys side-by-side:

...and here is a rough version of the two combined, showing the entirety of the leading hemisphere:

Great as per usual, Gordan.

I've updated my Iapetus 'bouncy' flyby movie, which is derived from a sequence of 203 frames; tweened to 406:

Imagine if you could rock Iapetus back and forth in your hand... well, this is the next best thing:

Great work Mike! wink.gif

I couldn't resist doing my own version of the CB/G/B composite:

I've just added some rough, RGB wide-angle views of Saturn and the storm to my Flickr account:

Just got back from London: drooled over Charlie Brown (not literally), gawped at Ralph's penetrometer -- and even touched a chunk of the Titanic's hull!

Oh, and here's a quick RGB composite from this latest, bountiful, batch of raws:

QUOTE (ElkGroveDan @ Feb 16 2011, 03:37 PM) *
That is just smokin cool! It must have been an incredible amount of work.


It looks more daunting than it actually is, thanks solely to the ability to record macros in Paint Shop Pro, as seen here:

http://www.youtube.com/watch?v=0XjW0vZZZXw

Most of the frames for the B&W movie were rotated, resized and rendered in a similar fashion while I was busy doing the washing-up! laugh.gif

Here's a merger of all of the frames that feature a moon; Callisto, alas, is sadly absent:

Thanks for the overwhelmingly positive feedback guys! I have done a colour version, using sequential G/O/B color frames:

http://www.youtube.com/watch?v=CPOrZvIZf08

I'm not entirely happy with it, because I can increase the frame rate by three if I use this sequence instead:

G/O/B
O/B/G
B/G/O

Stay tuned for further developments!
