I've been trawling through the PDS data and came across a really cool 10-image mutual event with Titan behind the sunlit rings and a very nicely resolved Epimetheus passing above, which they shot through R G and B filters at beginning and end and a couple of clear filter images in the middle, and am wondering if anybody out there feels like taking up the challenge of assembling this into a color animation. I've run the images through IMG2PNG and put them here. One example frame is attached. It'd be a challenge for sure but so cool if it worked...

Kudos!
This was already a lovely foreshortened view. I wonder if it will be even *more* 3D as a smooth animation ...bonus if in colour!

biggrin.gif That's because I set you the ones that are too tough for me!

From what I know of you Emily, nothing is too tough.

I haven't posted one of these in a while... A ring scan taken on January 23, 2010 by the narrow-angle camera, 7 footprints mosaicked. Click for a 3.5 MB version:



A higher quality PNG is available at my Flickr page along with some more info. Note the camera was rotated 3 degrees with respect to the ring "plane" and I have corrected for that above. The high res PNG is however at original orientation because any additional image transformations in Photoshop also cost me an additional image sharpness loss which I wanted to avoid as much as possible. With a lower quality JPG it didn't matter as much and it's probably more aesthetically pleasing this way, anyway.

Like the thread title says, exquisite! I love the Saturn-light along the bottom side.

There's also a tiny tiny little patch with a lovely double rainbow ( I'm too much of a ring muggle to say where. About 15% of the way from left to right )

I think it's visible in more than one frame as the orbital motion makes it keep up with Cassini's slew rate. I left them all in because they're kind of fun. That and I was too lazy to sort them out. smile.gif

I forgot to add there's also the corresponding right ring ansa scan, with the rings cut in "half" by Saturn's shadow. That one will have to wait, cleaning the cosmic ray noise in this one was quite draining.

As usual, on January 1 a few thousand Cassini images were released by the PDS. This release is in my opinion not quite as spectacular as these releases have frequently been but even so, there are some great ring observation sequences.

Some of the more interesting observations are hi-res movies of the F ring, including a 90 frame time lapse movie. The resulting animated GIF is too big to upload it here but can be seen at the Planetary Society website:

http://www.planetary.org/multimedia/space-...-in-motion.html

This animation is a 90 frame time lapse movie from rev 181 obtained on February 13, 2013 at a range of ~650,000 km. This is a high-phase observation. It starts at 14:14:15 and ends at 19:24:12. The interval between individual frames is 3:30 minutes. The images have been calibrated and their gamma adjusted to make the fainter parts of the ring more visible. Some of the more obvious cosmic ray hits have been cleaned up.

The images resulting from processing the PDS images are often more 'clean' than images from the raw JPGs (no compression artifacts or problems due to an automatic contrast stretch). I will be posting more from this Cassini release in the coming days.
