The upshoot is that star trails show rotation but show nothing in connection with earths orbit of the sun. Sounds silly, but I can't think of a good answer?
This movement of up to 1670km/hr is the explanation given for the star trail. Yet, in this same length of time (1 hour) Earth is also meant to have travelled 108,000 km on its journey around the Sun! That is more than 64 times the distance that is said to be photographed on a star trail picture. Why is this far greater movement not reflected in the star trail photograph? Answer - simple, because the movement does not take place.
I can't get my head round why the rotation is visable but the orbit isn't.
