The night sky is a beautiful thing no matter where you are..... Look at it and tell me that you do not just forget about every woe you have ever had. Gaze at the starry night and you forget about everything, get lost in the lights, and focus on the night sky. ...

A friend of mine from DOA pointed me into this awesome technique called 'Star Trails', which is using the rotation of the earth to create circles of stars in the sky when long exposed:
Besides of this picture he linked also an easy how-to:
As our planet Earth rotates around its axis every 24 hours, the star field that we see in our night sky rotates around the polar axis in a complete circle. Of course, in reality the star field is relatively stationary with respect to the Earth (over eons it is not, but in the context of our lifetime it is); it is the Earth that rotates about its own axis. Photographing this phenomenon is exciting and challenging.
In this article learn:
- all the information you need to take successful star trail photos.
- how to take these types of shots in a single exposure.
- techniques where one takes a series of short exposures rather than one long one.
- how to assemble the resulting images in Photoshop or some other application capable of automating this assembly process.
