About this image

I've taken a long exposure of Sirius and deliberately knocked the tripod slightly to create this light trail effect. Sirius is an especially good star for this technique as it is quite bright and low enough to be subject to the turbulent atmosphere. This effect also brings out the colours of Sirius' twinkling, spreading them out across the light path.

Quite stunning Steve. I really like this image and the similar light trail of Betelgeuse.
