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).

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. -------------------- |

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.
