Because it's a time-lapse photo with the lens pointed at the pollar north. Each star trace is only partial, as is evident in the photo. That concentric, circular look can't be achieved unless you aim the camera at either the southern or northern pole.
I do understand the north star and yes, its as partial trail due to only a 6 hour time lapse. I just expect to see some lateral movement or some deviation other than a perfect circle because our orbit shouldnt make perfect circle's.
See, you make statements like that without any reason. Why shouldn't it make it make perfect circles?
The earth orbit does precess, but over thousands of years, which is far too long for any tiny little camera to identify.
