Milky Way Rising with ISS Flyby

Time lapse of the rising Milky Way, shot at Sattelegg near Einsiedeln, Switzerland. Shot in the night of May 20-21 2020. Some frames had to be deleted due to bypassing cars.

Pretty much air traffic despite corona shutdown. Shot with a Nikon D850 on a SkyWatcher Star Adventurer mount with half star speed to pan along the horizon. Interval 25 seconds with MIOPS trigger.
