For last image I used the Star Spikes filter.

 From image easy to see that stars have counterclockwise direction of rotation. Our watch hands do not follow the star rotation direction; its follow the rotation direction of shadow of Sun. The shadow has the opposite direction to sky rotation. Even simple astro photo has a lot staff behind the scenes. This is why I like astrophotography.
