I've had two inqiuries in the last month for modern processed versions of the Voyager 2 Uranus and/or Neptune approach images, like the ones available for Jupiter (e.g. this one and this one) and Saturn (e.g. this one). Has anybody out there worked on Uranus or Neptune?

Yes, I'm fiddling with a Neptune movie, Emily. The Uranus sequence would be somewhat difficult to work with, I would've thought.

I am looking forward to it as well. There's just something about Uranus, Neptune, and Pluto that excites.

I'm still not able to process spacecraft images like the big leaguers can, due to the unavailability of batch .img to .png converters for Mac and the fact that I don't have Photoshop, but I can still whip up some stabilized image sequences pretty easily. I've wanted to do videos showing the relative speeds of the gas giants' atmospheres and their moons' orbits, while also demonstrating the decreasing bandwidth with each encounter. It's an approach I don't think I've seen anyone else try. 48 minutes per second would be ideal, because that's the speed you get when you play back the image sequences with the highest "frame rates" at 29.97 frames per second.

Very early look at what the Neptune sequence will eventually look like:

This is something I have wanted to do for a long time but haven't started yet. These images are much more difficult to process than the Jupiter images but I have better software now than back when I made the Voyager 1 Jupiter movie and this compensates a bit (in particular I can now use the SPICE C kernels to get the north azimuth).

What I would probably do is a movie consisting of fewer frames than Ian's movie above but it would be in full color. I don't know when I'll do this but I know it is possible.

Neptune in Voyager OGB color on June 7, 1989, 03:38:48 - 08:13:12. These frames were taken during the first continuous multispectral sequence. About ten frames per second, or five hours per second.

@Astroboy - did you get any farther with your Neptune sequence? Would love to see an updated version of that roughcut you posted (or a longer one showing Voyager looking back)!
