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. -------------------- Dr. Paul Schenk, Lunar and Planetary Institute, Houston TX

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! 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 always think before posting! - Marco -

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! -------------------- Dr. Paul Schenk, Lunar and Planetary Institute, Houston TX
