Aurora at OSP

On the last night of the Oregon Star Party we were treated to a display of the "Northern Lights". It wasn't very bright, but clearly visible to the naked eye. That is, we could see a very significant brightening on the northern horizon and sometimes pick out these brighter columns. I took 10 second exposures at ISO 6400 with a 35mm (focal length) lens at f/1.8.

In this frame we see several other things in addition to the aurora; an airplane, a meteor (probably a Perseid), a satellite, and some astronomers' red lights.
