Dione and Tethys in Passing
Vodpod videos no longer available.
Two of Saturn’s moons pass each other from Cassini’s perspective on December 6, 2010, in this animation compiled from 70 raw image files.
This was more an experiment in using iMovie HD to create an animation from a lot of individual images than anything else…I didn’t take the time to clean up the specks and streaks on each image, or align each frame to the next. It jumps about a bit more then I’d like, but at least I have another way of making animations now.
If you watch closely in 720p, you can make out the moons rotating, especially Tethys in the background. Keep an eye on Odysseus Crater as it edges closer to the terminator line…pretty cool! 🙂
