At any time of the year, it is not uncommon to look into a clear night sky and see the occasional meteor streaking through the heavens. However, with each orbit around the sun, our little blue planet passes through several meteoroid streams that can produce upwards of one hundred meteors per hour - a meteor shower. These streams are created by orbiting comets that shed cosmic particles as they approach the sun. Photographing these celestial events can be a challenge, but with a bit of knowledge you can improve your chances of success.
Knowing where and when a meteor shower will occur is the first step to a successful night shoot. These particles generally run parallel to the comet from which they came, and as such will appear to spread out from a single point in the sky. They are named for the nearest constellation or bright star from which they radiate. This 'fixed point' will track across the sky over the course of the night similar to the way that the stars do.
