09 Mar 12 - REMEMBER: When submitting to this pool, your shot must be of a star TRAIL. If a trail is not obvious in the thumbnail it will probably be rejected. Please read the Submission Guidelines if in doubt.
There have been an increasing number of star trails that have been fabricated from different pieces (e.g. a plane in the foreground and a star trail in the background). These creations are not disallowed from this pool, but we'd appreciate it if you'd indicate that you have fabricated it.

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.
SUBMISSION GUIDELINES: Please only post photos that contain star trails visible in the thumbnail in them. No moon shots, constellation shots, or deep sky stuff. There are other groups dedicated to those. If the Star Trails are NOT the focus point of the image - this is probably not the group for you. Reposts of the same photo will be denied. Repeat offenders will be banned.
This is a public group.
