The star trails move due to the ISS pitch axis which makes one rotation every orbit. If you look left or right of your trajectory, stars go in circles; look forwards and stars go in straight lines.
Whoa. Now here's a question I've never considered: which way is the ISS going and/or facing? Is there a "front," or is that determined by the direction of travel?
You said pitch, so is the ISS kinda rolling(like a ball, not side to side tilting lol) around the planet?
