Details:
Orion, The Hunter, has risen to our night sky here in Finland. And just after the hunter follows it's dog, Sirius, the brightest star on our night sky. It sends white light and when shining low on the horizon, disturbance in the atmosphere separates the different wavelengths.
With a long exposure and a little movement of the camera it's easy to see the effect. Many other stars make the same effect, but since Sirius is the brightest one, the effect is the most obvious.
I used Nikon D80 with 300mm/f4 Nikkor lens on a tripod. I had a spiral in my mind, but it turned out to be next to impossible with a 300mm lens. Often when the 20 second exposure had finished, all I saw was darkness and Sirius was far from the viewfinder. One of the frames where I managed to keep the star in the frame, after I had given up with the spiral figure and started to just randomly move the camera, I ended up getting a star-like shape, which I figured in the end fitted the picture and the whole idea quite nicely.
