The Voyager 2 Ariel image catalog

To create this montage, Ted Stryk stacked the best images of Ariel taken during each of Voyager 2's observations to increase their sharpness. The 13 observations center on the south pole during Voyager 2's approach, then shift over the pole toward Ariel's leading hemisphere. The largest image is shown at reduced resolution. The image immediately before that one was cut off at one limb (at the top of the view); Stryk used data from a lower-resolution earlier observation to fill in the missing portion of the disk.
