I decided to try and capture some of the Perseid Meteor Shower this year.  Instead of staying up all night with the good camera, I just stuck the GoPro outside and let it take 30-second exposures all night.  This allowed me to catch just a few meteors, and a lot of airplanes.  Since I captured the entire night, I removed all of the airplane shots and put together some star trails with the 4 meteors.
