An attempt at creating a time-lapse animation of Jupiter and its moons. Here you can see Callisto occulting Europa before they disappear off the screen and they are followed by Io. Shots were taken at intervals of two and a minutes on the night of 6th December 2014. 104 frames played back at 24 frames per second. Each frame made from a 500 frame video. Processing done in PIPP, Registax and Photoshop CS6.
