This photo captured the motion of the stars in 1 hour in which you leave the camera shutter opened for a while, if a car was passing through it would leave a trail of its light; this time I left the camera shutter opened for 1.15 hours. I let the stars do the trails as the earth spins, Same idea that the sun moves from east to west. The center point of the curves is actually the north pole which is the axis that the earth revolves around.
I also used a graduated filter, something like sun glasses on the lower part of the picture to reduce the amount of light coming from the bedouin house, as in a period of 1 hour light accumulation, the picture could have been burnt.
