Neptune from Voyager 2. Color is from images with CH4JS, green and orange filter.
Shadows of three moons are visible. Second image is with possible interpretation. -------------------- |

Yes!!! I was hoping you'd focus your imaging magic towards Neptune!

Beautiful! I have also worked with these images and interpreted the moon you considered Galatea to be Naiad, but other than that I agree with your interpretation.
Edit: One other question: Which color did you use the CH4JS filter for? It is even redder than the orange filter, but from your listing order it seems like you used it as blue. -------------------- |

CH4JS (with reduced contrast) was used as red color. Another ones: Orange -> green, green -> blue.
So this is false color, but corrected to approximately true color. -------------------- |

That makes good sense. I interpreted too much from the order you listed the filters.

Aaaahh... Neptune! I recall taping any mention of the Voyager 2 flyby on TV as a rather eager seven year-old.
Great picture Daniel. -------------------- |

...wow!
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Just so you know Machi, that new image will make its Outreach debut tonight, here in Kendal, in a talk being given to the 10th Kendal Cubs! (all ten of them!)

I can't help noticing similarity between clouds on Titan and the ones in that Voyager view of Neptune. In particular the biggest Neptune cloud with its north-south branch does resemble somewhat the big cloud recently seen on Titan. In general, and in both cases, the clouds cover only a small fraction of the globe and are predominantly in the form of long east-west streaks. Of course so much else about the two worlds is so very different. I have no idea whether the morphological similarity signifies anything interesting.

I'm not expert about clouds, so I don't know exactly if it's cirrus, but these are real clouds encircling Neptune's pole.
One of my future image will show this region with higher resolution. -------------------- |

Neptune with cirrus clouds swirling around south pole.
Slightly differences in color are caused by different kinds of filtered images (CH4JS, clear, violet and CH4JS, orange, clear). -------------------- |

Really enjoying this thread Machi.
At the time these images were first released I'd been backpacking through Europe for months and had totally forgotten about the Voyager Neptune encounter. One day on the streets of Paris I saw this incredible blue disk staring back at me from a news stand. I remember just standing there staring at it for ages - I just couldn't believe how compelling and unexpected all that atmospheric structure was! Now - back to that last image. Can I see a small bright/dark vortex thingy at the pole? Might we be looking at a miniature version of Saturn's 'evil eye'? P p |

"Really enjoying this thread"
I am glad to hear that. "Can I see a small bright/dark vortex thingy at the pole? Might we be looking at a miniature version of Saturn's 'evil eye'?" Maybe this little animation (1 frame = 5sec real time) give answer:
