Image sequence from the Cassini Orbiter
These two .gifs are of the same area on Saturn, at roughly the same time. How does Cassini do this? Two cameras? Nope. The probe snaps many photos in series, with a set interval between series. During each series of shots, as the camera exposes shots one after the other, using a different filter on the lens for each shot. This creates 3-4 “time lapse” videos of the same spot on Saturn, but at different wavelengths. This is useful to scientists studying the workings of Saturn’s atmosphere, since Different filters will highlight different gasses. I took this series of shots, divided them up by filter used, increased contrast and a few other things to highlight the differences. I was able to create a 9-frame time lapse gif of each filter.
