Star Trails

Photographer Christian Sasse shows how to create an image with star trails as the earth rotates around its axis by leaving a camera in a fixed position pointing upwards and opening the shutter in bulb mode.


The image above was taken in Arches National Park, Utah, in Spring of 2016 and shows a pattern of star trails in the Northern hemisphere.
The image below was taken in the Southern hemisphere from New South Wales, Australia. Sasse made it from a series of 30-second-long exposures, each taken 50 minutes apart, over 10 hours on April 28. He stacked those photographs using Startrails software, and then edited the final composite image using Photoshop. We can see circumpolar rings and also the Milky Way.
