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.

I had the same question and asked Mark. He replied:
QUOTE
I did extrapolate the orbit back to the Voyager era and search the images that were supposed to have captured it. Apparently it is just too small for the Voyager cameras. I seem to recall that their quoted detection limit was comparable to the size of Naiad, the smallest moon that they did find. This object is quite a bit smaller than Naiad.

By the way, the Uranian moon Cupid, discovered in Hubble images in 2003, was also too small for Voyager to detect.
