I own a motorola G5s+ and I was wondering if we shoot video in manual mode, is it possible to have the camera record star trails. If so, what settings would be ideal? How would you change them depending on the light pollution that night.

To create an image of star trails via video, use a tripod while capturing the video. Then process the video with ImageMagick:

convert video.avi -evaluate-sequence max output.jpg

Notes:

  • Aligning images shouldn't be necessary if a tripod is used. Stars may confuse alignment algorithm.

  • No need to extract frames of video prior to processing. ImageMagick can process the video file directly.

  • For evaluate-sequence, use the max or add methods because mean and median will cause the stars to disappear.
