The summer Milky Way over the Milk River Valley and sandstone formations of Writing-on-Stone Provincial park, in southern Alberta. On the horizon are the volcanic Sweetgrass Hills in Montana. The red tint at top is from an aurora active that night and the ground is partly illuminated by green auroral light from the north. The Summer Triangle stars are at top left. Sagittarius is on the horizon sinking into the low clouds at botton right which are illuminated by lights from Sweetgrass, Montana. Clouds and smoke from forest fires to the west cut down the transparency and clarity of the sky this night, especially toward the horizon. This is a stack of 4 x 3-minute tracked exposures for the sky, and 4 x 5-minute untracked exposures for the ground, all with the 15mm Canon full-frame fish-eye and Canon 6D at ISO 1000, on the iOptron Sky-Tracker unit.
The summer Milky Way with a meteor streaking at centre as a bonus. An aurora to the north off frame is lighting the foreground with a green glow. Haze and forest fire smoke obscure the horizon. I shot this at the Battle Scene viewpoint at Writing-on-Stone Provincial Park, in southern Alberta. Sagittarius and the galactic centre is on the horizon at left of centre. Capricornus is amid the haze at left of centre. On the horizon are the Sweetgrass Hills in Montana. The Milk River winds below amid the sandstone formations that are home to historic First Nations petroglyphs. This is a single 30-second exposure with the Nikon D750 at ISO 3200 and Sigma 24mm Art lens at f/2, taken as part of a time-lapse sequence.
The summer Milky Way in moonlight from a setting waxing Moon off frame at right and with deep twilight still lighting the sky, at the Battle Scene viewpoint at Writing-on-Stone Provincial Park, in southern Alberta. Sagittarius and the galactic centre is on the horizon at centre. Saturn is at far right. On the horizon are the Sweetgrass Hills in Montana. The Milk River winds below amid the sandstone formations that are home to historic First Nations petroglyphs. Clouds and forest fire smoke obscure the sky at low altitudes. This is a single 30-second exposure with the Nikon D750 at ISO 3200 and Sigma 24mm Art lens at f/2, taken as part of a time-lapse sequence.
