QUOTE (Ian R @ Dec 3 2010, 05:32 AM)  In the meantime, here's a four-frame clear filter mosaic: [attachment=23152:enceladus_mosaic.jpg] Wow, that is an absolutely gorgeous image! I love the ring in the background too!  (EDIT: Oh, now I see the "cheat" that you used that Emily mentioned - the background was changing as the images were being taken so you've smoothed that out) |

QUOTE (EDG @ Dec 2 2010, 01:26 AM) (BTW, what's up with the UV1 filter on wheel 2? The images of Hyperion taken through that have lots of white speckles on them) QUOTE (djellison @ Dec 2 2010, 01:31 AM) Could be that it's a very 'dark' filter (i.e. it's bandpass is either narrow, or well outside the best efficiency of the ccd, or both) and thus requires long exposure times and thus the raw unprocessed imagery is prone to noise. Yes, that's it - the UV1 images are always long exposure images and thus noisy. All (or possibly most - I'm too lazy to check it) of the UV1 images are like this. BTW lovely mosaics and color composites by Ian. |

There is a long series of images of a Tethys-Dione mutual event on the Cassini raw images pages. These images are just begging for an animation. (No, sorry, I can't do it myself now, I've got work to do
 .)

I made no effort to re-centre Dione (seemed a lot of effort for so many images). -------------------- -- Hungry4info (Sirius_Alpha)

Here's my version, making full use of the R/G/B filtered images:

I've re-compiled the video linked in my previous post based on a very good suggestion from Emily.
