A close-up panorama of a display of noctilucent clouds on the night of July 2-3, 2022 from home in southern Alberta. The bright sunlit NLCs in the high mesosphere contrast with the dark nearby and lower tropospheric clouds. This is looking north at about midnight local daylight time. This is a panorama of 4 segments, each 15 seconds at f/4 with the RF24-105mm lens at 80mm, and Canon R5 at ISO 400. There are wider versions of this same scene taken at shorter focal lengths to show the NLCs in context with the wider scene. This version shows the NLC's rippling wave-like structure.
A wide panorama of a display of noctilucent clouds on the night of July 2-3, 2022 from home in southern Alberta. The bright sunlit NLCs in the high mesosphere contrast with the dark nearby and lower tropospheric clouds. This is looking north at about midnight local daylight time. This is a panorama cropped from 8 segments, each 15 seconds at f/4 with the RF24-105mm lens at 65mm, and Canon R5 at ISO 400. Stitched with Adobe Camera Raw. There are close-up (80mm lens) and wider-angle (35mm lens) versions of this same scene.
The constellation of Andromeda with the famous Andromeda Galaxy (Messier 31) rising on an early summer night at Dinosaur Provincial Park, Alberta. This was June 30, 2022. The Square of Pegasus is at right. Several star clusters are at left: the Double Cluster at upper left, M34 below it, and NGC 752 to the right of M34. To the right of NGC 752 is the fuzzy patch of Messier 33, the Triangulum Galaxy. The main three stars of Triangulum are just rising above the hill at left. Green airglow tints the sky, as well as blue from the perpetual twilight at this time of year and latitude of 50° N. This is a blend of tracked exposures for the sky and untracked for the ground: all 2 minutes at f/2 with the RF28-70mm lens at 28mm and Canon R5 at ISO 800. The tracker was the Star Adventurer Mini. As the camera was aimed east to the rising sky, I took the static untracked shots first, followed by the tracked shots, so the ground would better cover the blurry horizon in the tracked shots -- i.e. the static horizon would be higher in the frame requiring less manual moving to cover the blurry horizon. LENR employed on all shots on this mild night. NoiseXTerminator applied to the sky.
