Star Trails Appear to Rotate in Opposite directions under the Dome due to Celestial Perspective

The stars precess and revolve around the North Star Polaris. Our celestial perspective on the amount of sky we can see depends on where we are and which way we are looking. The further one travels southward will cause Polaris to dip down closer to the horizon when facing the north. Once on the equatorial line, we view the star trails on a linear path. Therefore once one continues to pass the equatorial line, the star trails start to give the illusion of a counter clockwise rotation, as you can see demonstrated in this video.
