A composite showing about three dozen Perseid meteors accumulated over 3 hours of time, compressed into one image showing the radiant point of the meteor shower in Perseus. This was August 12, 2021, from The Trail of the Fossil Hunters trailhead lot in Dinosaur Provincial Park, Alberta. A dim magenta aurora is visible to the northeast at left. Cassiopeia is at centre above the radiant point; the Andromeda Galaxy is just right of centre. Capella is rising at left. Airglow also tints the sky. This is a blend of: a single 30-second exposure for the background sky, one with the aurora at its most active, such as it was this night, with a stack of 8 x 30-second exposures for the ground to smooth noise. Then 32 x 30-second exposures for the individual meteors (a couple of frames have two meteors on them) are overlaid with Lighten blend mode onto the base sky image, each with masks to reveal just the meteors. All frames were with the Canon R6 at ISO 6400 and with the TTArtisan 11mm fish-eye lens at f/2.8. The camera was on a static tripod, not tracking the sky, so I hand-rotated all the meteor frames around Polaris at upper left, to bring them into close alignment to the base sky image, so the positions of all the meteors are close to their actual positions in the starfield when they appeared. A couple of exceptions were the meteors at bottom which appeared in Taurus, below the horizon at the time the sky image was taken, so those meteors are moved up artificially. ON1 NoNoise applied to the sky image. Ground illumination is from starlight.
Sunset at Vermilion Lakes, Banff, Alberta, over Mt. Rundle reflected in the still waters, on an evening with a smoke-filled sky from B.C. forest fires. This is a single shot with the Canon EOS Ra and 15-35mm RF lens.
The galactic core area of the northern summer Milky Way over the Blakiston Valley and Blakiston Creek in Waterton Lakes National Park, Alberta on a July night. Sagittarius is at left over Vimy Peak, with the bright Sagittarius Starcloud over the valley, with the Messier 6 and 7 star clusters low and left of centre. Scorpius with reddish Antares is at right. The pink Lagoon Nebula, M8, is at top, and the globular cluster M22 is at upper left. The dark Pipe Nebula is at top centre. This is a blend of tracked exposures for the sky and untracked exposures for the ground: a stack of 4 x 2-minute tracked at f/2.8 and ISO 1600 for the sky, blended with a stack of 2 x 5-minute untracked at f/4 and ISO 1600 for the ground. A tracked 2-minute exposure through an Kase/Alyn Wallace Starglow filter adds the star glow effect. An additional 8-minute exposure at ISO 400 and f/8 taken early in the evening during blue hour adds some illumination to the distant mountains. However, the majority of the landscape comes from untracked exposures taken just before the tracked ones when the sky was dark, with illumination just from starlight with a more normal colour balance. Forest fire smoke moving in added some haze and lowered contrast. The bright light is the Prince of Wales Hotel, and the light to the left is from the golf course clubhouse. The sky tracker was the Star Adventurer Mini which worked perfectly. The camera was the Canon ESO Ra and lens the Canon 15-35mm RF at 35mm.
