Star trails with a Samsung S23 smartphone on tripod last night over 4hr 33min shot, hyperlapsed x300 to 54 sec. You can see some satellite streaks and perhaps one meteor streak as well as clouds. Still shots show start position with annotation with Polaris (North Star) close to the center or rotation. Since Polaris isn't exactly at the celestial North pole (direction earth's axis points to in the heavens) and is about 0.7 ° off, Polaris also moves in a very small circle .. just noticeable. Also the earth's axis of rotation slowly wobbles (precession) over many years. In the 41st century, our earth's pole will point to a new "north star" , γ Cepheus shown in the pict.
