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...

Taking up Emily's challenge...
Phase 1: Put together the images as a simple animation set....done 
Full size version here 1.68mb Phase 2: Take the images apart and recompile as separate elements, combine the RGB to use as the basis for colour and then pull those together through Adobe Premier to create a smooth animation using all of the elements....working on it  Check back soon! You do set some tough one's for us Emily!!

I wonder if it will be even *more* 3D as a smooth animation ...bonus if in colour! -pjam -------------------- "We absolutely must leave room for doubt or there is no progress and there is no learning." -Richard P.

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.
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. -------------------- |
