No this is not faked! I put it together from a set of departure images. only about 10% or so involved use of a duplicate
image to fill a gap. It took a lot of heavy processing to suppress Neptune glare, which caused some of the spots to go oversaturated and some of the finer ring detail to wash out but its still a pretty pic. I dont think Triton was in the vicinity at the time, which would have been a real kicker.

I made this in 1993 and its been lurking in my digital files ever since. its a wonder it didnt "disappear" with all the OS and platform changes since then.

Wow! blink.gif That's beautiful. How come we've never seen that before?! That should have been in every astronomy book written - and every Outreach talk I've given - since you made it! smile.gif

Wow!! I didn't have even the faintest idea the Voyager 2 dataset contained images making a mosaic like this one possible. Almost looks like a completely new planet to me ;-).

Beautiful! Brilliant processing. As someone who has looked at those images before, I can attest to how difficult they are to clean.

Very pretty Dr. Shank - like a second Saturn lurking in the outer solar system. Here's an example of the "original" imagery that I recall:

http://photojournal.jpl.nasa.gov/jpeg/PIA02224.jpg

I think some of the ring arcs were missed as the left and right (unshown) sides were taken at different times. Guess we'll need a new mission to address that?

I am amazed too, Paul! cool.gif Can you pls give us further detail on such picture (original images, filters and so on...)?
This is a very faive processing, done in order to remove some noise/dither and improve contrast. I slightly enhanced colors and, in fact, rings are reddish and planet blue!

color is artificial and not true in this mosaic. no color filters were used. As far as the ring arcs, they had rotated out of view each time an image was taken, which was a span of several hours!

I started working on it too but realized that the inner ring is so close in image depth to the noise that its nearly impossible to remove one while keeping the other (without sectioning the image and adding artistic license) so I realized that's why Paul left it the way it was.
