The arch of the Milky Way mirrors the sweep of the Red Deer River on a magical night in the Alberta Badlands.
Images of the Milky Way arching across the sky are now iconic. They are almost always assembled from individual frames stitched together to make a seamless panorama.
From the northern hemisphere, spring is the best season to shoot such a panorama as the Milky Way then remains confined to the eastern sky.
Later in summer, when the Milky Way passes directly overhead, panoramas are still possible, but the Milky Way looks distorted. The process of mapping a round sky onto a rectangular image, as I show here, inevitably stretches out the Milky Way near the zenith.
Last Saturday, in search of the Milky Way during prime panorama season, I set up for the night at Orkney Viewpoint overlooking the Red Deer River in the Alberta Badlands north of Drumheller. There, the river performs a grand curve through the valley below.
Above, the Milky Way, often described as a river of stars, sweeps in mirror-image fashion above the earthly river.
The panorama above contains the reflection of stars – of the constellation of Delphinus in particular – in the smooth water on a windless night.
To the north at left, the Northern Lights put on a subtle show. While never spectacular to the eye, the camera records the aurora’s colour and forms that often elude the naked eye.
The display was brightest early in the evening – that’s 11 p.m. now in May at my latitude.
The display then faded in intensity before I shot the two panoramas about 1 a.m., but the last few frames of the time-lapse show a final burst of colour from a lone curtain reflected in the river.
This was a magical night indeed. And a rare one this spring with clouds more often the norm at night.
The next dark of the Moon coincides with summer solstice. So while the moonlight won’t interfere, critical for shooting the Milky Way, the glow of perpetual twilight at my latitude will. The Milky Way will be set in a deep blue sky.
By July’s dark of the Moon the Milky Way will be high overhead, making panorama arches tough to assemble. It looks like this might have been my one best night to capture such a scene this year. But it was a good one.
