1 hour & 10 minutes duration for star trails. Looking NE from the VCO.

Location: Victoria Center Observatory, Observatory Hill, Saanich, BC, Canada

It was a beautiful warm evening as I joined a few fellow observers at Victoria Centre Observatory to visually observe the Perseid Meteors. Although no meteors appeared in my photos, I observed about a dozen Perseids per hour. The International Space Station streaked across the northern sky past Polaris just before midnight, and appears in this star trails photo. The bright white star trails in the centre of the photo are Cassiopeia.
