Similar pictures were taken in 2004 in the USA, see https://www.satsig.net/geopics.htm
With really dark sky, long time exposure and high resolution you can see the movement of satellites in inclined orbit and even see older inclined orbit satellites tumbling, having lost attitude control. The super high resolution pictures are here https://www.noao.edu/outreach/press/pr01/0106images.html
Anyone with a good camera and time exposure should give it a try. Put the camera on a solid rock!
Best regards, Eric.
