This is in my local paper website.
The guy claims to have captured these images over 20 minutes and he claims they were not moving.
What do you guys think?

I can do this easly with a camera and a RC airplane. This guy set his exposure time SUPER low and than flew the airplane in a circle to make the mushroom formation we see in the picture.

He keeps calling his camera a Canon EOS 60D.
Should be D60, strange error to make.

If, as it says on the article, that's a 20 minute exposure, where are the stars? Stars would have left trails while they were moving during those 20 minutes.
Unless we are seeing the stars, and as the lights appear out of focus, I guess that's a possibility.
This is not a 20 minute exposure.
stars are dots, not streaks.
Google image search red sprites.
Stars will streak with a 2 second exposure.
One of the photos (the one with the three lights) is a 20 minutes (in fact, it's almost 22 minutes) exposure.

The dots are noise, you can see them in front of the trees in the uncropped version.

Only with a very large telephoto lens, in 2 seconds the stars move just 0.0083º across the sky. I have photos in which the stars started to make streaks, but it was a 30 seconds exposure.
