About Star Trails

Send in your shots of star trails of the night sky to share with everyone. All you need is a camera with long exposure setting, a tripod, cable release, and some clear dark night skies.

In as little as 5-10 seconds in a telephoto lens, or 30 to 90 seconds with wide angle lenses - you will start seeing those telling star trails that trace the movement of our planet through the heavens.

To see trails that rotate around a central point - look to the celestial poles for the centre of rotation. Polaris (the North Star) in the Northern Hemisphere, or a region near σ Octantis - pointed to by the Southern Cross in the southern hemisphere.

I suspect there could be some incredible long exposure star trail imagery from the equator using 180 degree fish eyes - where both poles are in the image!

Here are three links to get you started on taking great star trail (a.k.a. star streaks) shots.

NOTE: Please only post photos that contain visible star trails in them. No moon shots, constellation shots, or deep sky stuff. There are other groups dedicated to those.
