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!! 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.

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!

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.

If Occam had heard my theory, things would be very different now.
