Aperture:f/4.5
Focal Length:10mm
ISO:1600
Shutter:45 sec
Camera:Canon EOS 60D

It’s rare to get such a clear night in the mountains, but last weekend, July 6-7, provided a couple of ideal nights.

This image combines about 180 exposures, each 45 seconds long, stacked to create a single image of long star trails setting into the west behind Bow Glacier in Banff. The result records the sky’s motion over nearly two and a half hours. Running at right angles across the descending stars are vertical streaks from a bright meteor (left) and a satellite (top, centre).

Light from the rising waning Moon provides the illumination.
