I took 3 minute exposures and the anomaly is in 3 of my photo's, so I doubt it's a satellite or a plane.
The date on the photo's are 2025-03-17 ranging from 23:07:06 to 23:14:09.
The calibrated xisf files can be downloaded here.
So if you look at the attached file, it's the streak that I'm curious about.
Thanks in advance
Edwin
