Shooting star

During last year's Perseid meteor shower I was practicing with my scope under a fairly light pollution-free night sky. Whilst I was taking a 10 sec long exposure shot luckily a meteor crossed my narrow field of view and this was captured. Not satellite for sure because the trail is rather greenish-blueish. Different elements burn with different colour, but I never went that far to find out which elements are responsible for this show :)
