Dec 20-21, 2019 time lapse plus star trails Some people mark the shortest day, but I always look forward to the longest night (tomorrow). This time lapse contains 2,877 frames captured over 13+ hours between Dec 20, 2019 at 5:16pm MST – Dec 21, 2019 at 7:02am MST. There’s a Starlink satellite constellation overpass near the start. It’s more obvious in the star trail version.
