For a long time, I have tried to pull detail out of the outbound sequence Voyager took as it receeded from Triton. The closest imaging covered an area of the polar region poorly seen during the inbound flight.
These are constructed with the two best image sets, excluding those that are so high phase that only atmospheric features can be seen. The image on the left is a composite of wide angle views and a single narrow angle frame, the highest resolution view of the outbound sequence, when Triton was still more than frame filling. Unfortunately, it is seriously underexposed. The image on the right is more distant, and is a super-res stack of four narrow angle frames. While the resolution is lower, the signal to noise ratio is much better due to having narrow angle images to stack and better exposed images. These are reprojected versions of the two images. On the top image, several craters and other topographic features are apparent, including some things that resemble the "frozen lake" type features seen during hte inbound sequence. The lower version, while overall of lower resolution, shows much more detail around the terminator, inculding another of the "frozen lake" features less apparent though visible in a close examination of the upper image (this is due to the fact that the terminator region was more effected by the sever under exposure of the upper image. This is a work in progress, but is clear that these images give us a peak at another region of this elusive world. -------------------- |

Nice I have very fond memories of the V2-Neptune encounter; in a pre-internet era the USA channel had a special "Neptune Up All Night" program where they broadcast pics from the encounter live as they came in, along with interviews. Stayed up watching it, recorded to VCR, and played back and studied the good bits (mostly Triton). Good times

Very impressive, Ted.

Could anybody show the region on a map, maybe I should add it to the triton map at http://www.solarviews.com/eng/trimap.htm

I am trying to figure that out. Before my crash I had a map, but I don't have it anymore. It was from the 1990 Science reports on Triton.
Here is an improved version of the image....I cut back some noise near the terminator in the higher resolution image, giving preference in that area to lower resolution but higer SNR data. -------------------- |

I would be able to take a shot at showing these on a map if we can determine the exact time the images were taken. -------------------- Steve [ my home page and planetary maps page ]
