The Milky Way rising over the peak of Mt. Blakiston, in Waterton Lakes National Park, Alberta, Canada. This was June 10/11, 2024, so some snow still remains at high altitudes. This is an example of a "deepscape" — a nightscape taken with a longer focal length lens than is usual for nightscapes, to frame a fragment of a landscape below an interesting area of sky with notable deep-sky objects. In this case I used a modest 70mm telephoto lens to zoom into a section of the Milky Way in northern Sagittarius and Serpens, framing the bright Small Sagittarius Starcloud, with the pink nebulas Messier 17 and Messier 16, aka the Lagoon and Eagle Nebulas, above it. The star cluster Messier 25 is to the left of the Starcloud, which is catalogued as Messier 24. This was from the Red Rock Canyon parking area and trailhead. I was the only person there this fine night. Some clouds to the east darken the sky at lower left. The waxing crescent Moon was setting low in the northwest opposite this scene, and was providing some illumination to the peak. This is a blend of two exposures: - a single untracked 2-minute exposure at ISO 1600 for the ground, - and a single tracked 2-minute exposure at ISO 800 for the sky, taken immediately after the foreground image, with the tracker motor now on. One shot only here so not stacking; while I took more tracked shots the sky was moving behind the peak making those frames unusable. Both frames with the Canon RF28-70mm lens wide open at 70mm and f/2 on the Canon R5, which was on the MSM Nomad tracker. The tripod was not moved. I used Long Exposure Noise Reduction to take dark frames in-camera, to eliminate the hot pixels the R5 is prone to in long exposures. No filter was employed. ON1 NoNoise AI applied to the ground; RC-Astro NoiseXTerminator and StarShrink applied to the sky. Satellites cloned out. Mild special effect finishing touches added with Nik Color EFX and Radiant Photo plug-ins.
