Star Trails at Maryhill Stonehenge
The Maryhill Stonehenge in Washington is a full-size, astronomically-aligned replica of the original Stonehenge in the UK. It was dedicated as a memorial to those that died in World War I.
This image was created by stacking thirty nine photographs (about 3 hours 15 minutes of shooting) shot after midnight. The centre of the circles is the North Pole Star. If you notice closely, you can even see some Perseid's meteors.

I shot 39 RAW images and converted them into JPG using Lightroom. Then I used a program called StarStaX (Windows users can use Startrails.exe) to stack the 39 JPG images. Finally, I opened the stacked image in Photoshop and touched it up.
