Whether it was a Heliocentric or Earth centred system, the same parallax would be observed. This was decided here long ago. Parallax is not involved for the star trails being discussed concerning the North star as I thought all had agreed that the effect of the parallax ellipses were too small to be detected with ordinary photo equipment.From GWW.Philip.
