For the star time-lapses I currently mostly use a Nikon D850 with Nikkor 14-24 mm f/2.8 lens and sometimes a Nikon D3 with 17-25mm f/2.8 lens. Panning is done with the SkyWatcher Star Adventurer mount at half star speed. The PhotoPills app helps align the camera with where the Milky Way is at what time, so that it moves nicely through the frame during the shot. I use the MOIPS Trigger as an intervalometer and take a picture every 25 seconds. The camera's built-in intervalometer locks the camera and you can't adjust the settings in between. On an Android tablet connected via USB runs QDSLDashboard, monitors the histogram of the shots and controls shutter speed and sensitivity for the day/night transitions, maximum 20 seconds and ISO 6400. Editing the images is done with Adobe Lightroom and LRTimelapse with which seamless transitions from day to night, brightness, changing colour temperature, deflickering and exporting as a movie are made. Some videos are further processed with Apple iMovie. More videos are on my YouTube channel.

Passing by clouds are cool for timelapse photography but not for observing the stars through a telescope. Light pollution in Switzerland has increased over the last 30 years. Here in the first part of the movie the yellow clouds are illuminated by the nearby city Chur. In the second part one can see the light dome of the huge italian city Milano. The clouds further away are dark and then turn yellow when they get closer. Also visible is the light pollution caused by the catholic church of Ladir which is like the church of Falera illuminated almost all night for no reason. At least they turn it off at 1 o'clock at night. Electricity is way too cheap.
