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.

If I am remembering this correctly, when Voyager 2 flew past Triton, Triton was the most distant known object in the solar system. Pluto was near perihelion and closer to the Sun, and the KBOs we know today had not been discovered yet. Triton was beyond Neptune and Nereid was closer to the Sun.

Actually there would have been some Neptune-lit terrain visible to Voyager during the close Triton flyby- the sunlit terminator extended to about 40 degrees north, but the Neptune-light terminator would have reached ~90 degrees north, and the intervening parts of the northern hemisphere were in direct view from Voyager 2 on approach (as Voyager was coming almost directly from the direction of Neptune). Lighting was poor, though- Neptune was a crescent as seen from Triton at the time, and of course even sunlight illumination was challenging for imaging with Voyager's vidicon at Neptune. I don't recall seeing any successful detection of Neptune shine on Triton in the Voyager data.

Ted Stryk did got a huge amount of neptuneshine on Triton but it was on a low res departer image, and i like some higher quality neptuneshine even if its just a part of it and not all of it

where is the pole, i tried reprojecting this (above (link) before but i think my attempt was wrong so where is the pole?
