Emerald Trails
Emerald Trails
At over 62° northern latitude, the celestial north pole is really high in the sky over Yellowknife in the Northwest Territories. In Seattle, by comparison, the celestial pole is about 47 degrees above the horizon. 15° may not seem like much but visually you really notice the difference. The star trail image you see here was captured over the course of about 35 minutes. The emerald background is courtesy of the aurora. Polaris, the North Star (which is not exactly at the celestial north pole), is the bright star closest to the center.
