Here's my time lapse spanning the best 45 minutes of the Great Conjunction that I was able to observe. Played back at 15x, 30x, 60x and 120x realtime. If you watch the fastest versions of the video you can see the moons of Jupiter and Saturn moving through the frame. Each frame was automatically aligned on Jupiter and stacked in 0.5 second segments to make up the frames of the time lapse.
