The Milky Way of Spring on the Prairies

Summer Milky Way over Field (May 2013)

Late on a clear spring night on the Canadian Prairies the Milky Way rises over a fallow field.

Despite taking this not 200 feet from my home, this isn’t a view I see or photograph very often. In spring on the Canadian Prairies, it seems we go from dark winter nights to the bright skies of mid-summer with little in between to mark spring. Miss a dark-of-the-Moon period in late April or early May and you miss the opportunity to see and shoot this sight – the summer Milky Way rising late on a dark spring night, with Scorpius due south. In another month this same sky will be washed out by the glow of perpetual twilight around solstice.

By July or August when dark skies return, the Milky Way will be already well up at nightfall, and Scorpius on the way down past his prime for the year.

But in this shot, taken at 3 am this morning, during a welcome run of clear moonless nights, I framed Scorpius at lower right skimming the southern horizon as high as he gets from western Canada. The yellow star at lower right is Antares, the heart of the Scorpion. To the left of Scorpius, the spectacular starclouds of the summer Milky Way span the sky from Sagittarius in the southeast to Cygnus high in the east at upper left.

Around me now, farmers are beginning their work of tilling and seeding the fields. But this one will likely lay fallow this year, the furrows seeming to extend off into the distant Milky Way.

This is a stack of five 2.5-minute tracked exposures, but with the ground included from just one of the exposures, to minimize the blurring introduced by the moving camera. The lens was the wonderful 14mm Samyang, a manual lens that doesn’t register in the camera’s metadata, thus the reading at left that this was taken with a 50mm lens, the default setting when the camera doesn’t know what optics it is connected to.
