The nights were short and never fully dark, but early June provided a run of clear nights in the Rockies to enjoy Mars and the Milky Way.
Weather prospects looked good for a run of five nights last week so I took advantage of the opportunity to shoot nightscapes from Banff and, as shown here, in Yoho National Park across the Continental Divide in B.C.
The lead image above is a sweeping panorama at Emerald Lake, one of the jewels of the Rockies. Though taken at 1:30 a.m., the sky still isn’t dark, but has a glow to the north that lasts all night near summer solstice. Even so, the sky was dark enough to reveal the Milky Way arching across the sky.
The mountain at centre is Mt. Burgess, home of the famous Burgess Shale Fossils, an incredible collection of fossilized creatures from the Cambrian explosion.
The image is a panoramic stitch of 24 segments but cropped in quite a bit from the original, and all shot with an iPano motorized panning unit. Each exposure was 30 seconds at f/2.2 with the Sigma 24mm lens and Nikon D750 at ISO 4000. One short exposure of the lodge was blended in to reduce its light glare. The original, stitched with PTGui software, is 15,000 x 9,000 pixels.
The view above, a single frame image, shows the view to the south as the Milky Way and galactic centre descend toward the horizon over the south end of the lake. Lights from the Lodge illuminate the trees.
The next night (above) I was at the same spot to shoot Mars in the deepening twilight, and reflected in the calm waters of Emerald Lake, with Cathedral Peak at left.
Another multi-frame panorama, this time sweeping up from the horizon, captures Cassiopeia (the “W”) and the rising autumn constellations reflected in the lake waters.
Vega is at top, Deneb below it, while the stars of Perseus and Pegasus are just rising.
It was a magical two nights in Yoho, a name that means “wonderful!” Both by day and by night.
