An individual star trail study
The above image is used with permission of Rob Packer Photography.
If you check out his website, you will see the method used. Briefly, he took 625 individual photographs over a period of 5 hours, and then overlayed them using photoshop to produce the final composite image.
This is an interesting image in a number of ways.
Firstly, it was taken in the Southern Hemisphere, which means that Polaris was not the 'target', but instead the Southern Celestial Pole.
Secondly, aswell as the circular star trail, we can see several straight line trails, which are caused by aircraft arriving and departing from various airports along different flight paths. This begs the question, that if Earth rotates, why is the flight path straight? Of course the usual response is that somehow, the entire atmosphere moves in exact synchronicity with the Earth. We have seen elsewhere that not only is this not possible, but that the theory itself is flawed.
