The galactic centre region of the Milky Way in Sagittarius setting behind Bow Glacier at the end of Bow Lake, in Banff National Park, Alberta. This was in the deep blue of the start of morning twilight, despite this being at 3 am. This was before dawn on July 17, 2018 on a very clear night. Saturn is just above the glacier and is the main reflection in the water. This is a stack of five exposures for the ground and water, mean combined to smooth noise, and one exposure for the sky and reflected stars, all 30 seconds at f/2.5 with the Sigma 20mm Art lens and Nikon D750 at ISO 6400. All with LENR on. An ON1 Photo RAW Glow effect added to the sky and reflection. Zone System Express unsharp masking /sharpening and vignetting applied.
Bright planets Mars (reddish at left) and Jupiter (right, over Bow Glacier) over Bow Lake, in Banff, Alberta, and reflecting in the water in glitter paths on the lake. A third planet, Saturn, is also present as a modestly bright star just (!) above the ridge of Bow Peak in a notch left of centre, below the satellite. Moments later it disappeared behind the mountain. This was in deep twilight as the Milky Way was beginning to appear. I began a time-lapse shortly after this. This is a stack of 8 x 10-second exposures for the ground, mean combined to smooth noise, and one 10-second exposure for the sky, all with the Laowa 15mm lens at f/2.8 and Sony a7III at ISO 3200. This was July 16, 2018 on a perfect night at Bow Lake.
The Milky Way and Galactic Centre (right) and Mars (at left, near its brightest for 2018), over the Bow River and Bow Valley, looking south and west to Storm Mountain and the Vermilion Pass area of the Continental Divide in Banff National Park, Alberta. Saturn is amid the Milky Way at right. This was July 15, 2018. The lights at left are from the Castle Mountain interchange at Highway 1 and 93. This is a stack of 8 exposures, mean combined to smooth noise, for the ground and one exposure, untracked, for the sky. All 30 seconds at f/2.8 with the 24mm Sigma lens, and Nikon D750 at ISO 6400. The frames were taken as part of a time-lapse sequence. Dynamic Contrast filter from ON1 applied to the ground, and Soft and Airy filter from Luminar applied to the sky for a soft Orton effect.
