This is an image of elegant trails traced by the stars seen in the Northern Hemisphere as planet Earth rotates on its axis. This image was made on 2009 February 24 from Estremoz in Portugal. The above image was constructed from about 80 consecutive frames taken with a tripod-mounted Nikon D200 SLR camera and a 18mm lens over one hour.<o:p></o:p>
