A different type of star trail image.

[Xilman]

 

 

Images of star trails are very commonly seen. They are generally taken with a stationary camera and use the Earth's rotation to let the sky and stars drift past the camera.

This one is different. It uses a moving camera to follow the sky and it lets the star drift past the sky.

Barnard's star has an enormous proper motion of 10.3 arcseconds per annum. The stack of subs in the image shown above started on 2019-08-30 and ended on 2023-08-07 for a duration of just a tad under four years. The star had moved 41.2 arcsec in that time. To put it in context, that is roughly the apparent size of Jupiter.

Added "camera" after "stationary".

Great capture of proper stellar motion. It’s hard to believe that our seemingly eternal constellations are transient on a cosmological timescale, but there goes your proof.

Awesome piece of work.
