Daniel Machácek does some modernizing of old Voyager 2 data at neptune. You can clearly see a shadow of one of Neptune’s moons at the top right edge and two others in the same area that are much less obvious. Interesting thing about data is that it is often better than the processing technology that happens to be available at the time the actual missions took place. Add to that the fact that there is a small army of talented freelance imagers like Daniel, the result is what feels like new images from old missions.
