I was just wondering if someone has "super enhanced" the Voyager 2 images of Neptune's largest moon Triton and made them available to the public? I've read about and seen it done on Voyager images of Saturn's moons. Considering there won't be an orbiter going to Neptune being launched for a long time, this could be very worth while idea.

I have been doing some work on Triton, slowly. Malmer had a really good Trition image as well. It is one of the best Voyager data sets in terms of coverage, but has some problems with smear and spacecraft motion.

Here are some of my favs... global views

And best of all

Thanks Decepticon

Lovely...
Beautiful...

But were has this orange hue gone?

The orange, turquoise and violet colors were the most astonishing and impressive features,
when I first saw the images in 1989:
'Wow, so far away from sun and then these colors.'
Actually images from less distance didn't show them in this color strenght any more...

Why? False color imaging? What are the natural colors of Triton?

Bye.

Looks to me like like it is a color balance issue. And, remember that since it is Voyager data, there is no red, so the color will be shifted with either Green or Orange substituted for red.

Result from cooperation with Ted Stryk. Triton animation from four Ted Stryk's processed images (from Voyager 2 WAC camera). Framerate is one frame per 2 seconds. Images are magnified 2x. Time from 1989-08-25T08:15:09.000 to 1989-08-25T08:39:09.000.

Download link is lower. Old animation with wrong colors was deleted.

Very nice images Stefan! Especially second one. One of the best Triton crescent images which I ever seen. But try remove color noise from image (speckles in image). Best way is perhaps manually removal. Than this image will be perfect.

I send improved version of Triton animation. Past version had wrong colors (problems with colorspace in encoder).

Thanks, perhaps I'll find time to improve it.

Excellent work animating this!

I've often wondered which Voyager picture Candy Hansen used in the following video to demonstrate how tectonic activity may have altered Triton's surface:

Well, I've found it -- it's a crop of image c1139623.png:

In the video linked above, Ms. Hansen disects the image twice, moving the resultant pieces to reveal an ancient and degraded impact feature:

i had forgotten about this idea long ago. interesting but the difficulty has been that any number of cuts and rearrangements can be made on this surface and none are truly unique or diagnostic. this terrain is not easy to work on but it is comprised of lots of adjacent closed and partly open circular features of similar size, a characteristic of diapirism (think salt domes or convection) not impact craters.

I agree. It was an interesting idea, but different cuts and moves might create different apparent craters.

I played around with it when I was working on the images for this post and noticed the fact that multiple alignments seemed to work. http://planetimages.blogspot.com/2009/08/m...ton-images.html

By the way, here is my version of the last set before Triton filled the frame:

A long time ago, nearby a planet far far away ...

Triton hi-res mosaic from Voyager 2 spacecraft.
Color is from wide angle camera images (color from violet, green and synthetic image).
True resolution of images is between 0.7 to 1.05 km/pix (BW images) and 3.5 km/pix for color images.
One version is with backround WAC image and other is without it and rotated by 90 degrees (so south is approx. down).

Second image:

Those are beautiful as usual, machi. Do you see any correlation between color and morphology?

Rather not. It looks that most of color differences are caused by deposits from atmosphere (brown-orange are methane ices? and bright blueish are nitrogen ices).
During processing, I found only one darker spot in rough terrain (cantaloupe? terrain), which can be directly matched with some type of morphologic unit.
Then bright ice deposits line the border of south polar ice cap and southern terrain is full of curvy units, which are more brownish (so presumably they contain more methane ices, geysers occurs in these regio). This terrain have not significant topography.
But more interesting terrain is near terminator. I see terrain which looks like hybrid between Martian and Europaean terrain. Some regions looks like chaos terrain on Mars, some even with glimpse of outflow.

Awesome work, these are keepers. Love the colors, too.

I also love the colors- they ring truer, somehow, than other versions that I've seen. I also love the almost seamless blending of the NAC and WAC images. Nice job!

Spectacular! Wow, I never thought of merging the WA images with the earlier high-res images. I just used it to place the highest resolution shots. http://planetimages.blogspot.com/2009/08/m...ton-images.html I reprojected them into earlier images http://planetimages.blogspot.com/2009/08/s...rs-since-i.html

I am in awe.

i still wonder what the rest of Triton looks like . . .

Greetings,

Thought I'd post here an updated version of the feature overlays on my Triton map. I'll have to consider adjusting the color based on the above images.
