Comet NEOWISE (C/2020 F3) with a small display of noctilucent clouds over Emerald Bay and the iconic Prince of Wales Hotel at Waterton Lakes National Park, Alberta, at dawn on July 14, 2020. This was from the new International Peace Park viewpoint near the marina. Capella is at upper right. This is a blend of a stack of four exposures for the ground and water to smooth noise, blended with a single short exposure for the sky, all 20 seconds at f/2.5 and ISO 400, plus an additional short 8 second exposure at ISO 100 blended in with a luminosity mask to reduce the intensity of just the hotel lights and prevent them from overexposing too much. All with the 35mm Canon lens and Canon 6D MkII camera. LENR employed on all shots to reduce thermal noise this warm summer night.
The galactic core area of the Milky Way over Waterton Lakes National Park, Alberta with the pairing of giant planets from summer 2020. Jupiter is the bright object at centre, with Saturn dimmer to the left (east) of Jupiter. In 2020 the two planets were close together in the summer sky. Sagittarius is at right. The Prince of Wales Hotel is the bright light source. This was July 13-14, 2020. This is a stack of 10 exposures for the ground, mean combined to smooth noise in the dark foreground, with the sky from one exposure, all untracked for 25 seconds at f/2 with the Sigma 20mm lens on the Canon EOS Ra camera at ISO 3200. A single short exposure is blended in for just the hotel lights to prevent them from being too overexposed. Stacked, masked and blended in Photoshop.
Comet NEOWISE (C/2020 F3) with the Northern Lights and a STEVE arc aurora to the left, all over the Waterton River at Waterton Lakes National Park, Alberta, on July 13-14, 2020. This was from the Maskinonge picnic area. The Big Dipper is at upper left. A very faint green picket fence aurora is at right above the comet, a characteristic of STEVE arcs. This was an astounding night for sky phenomena! This is a blend of a stack of six exposures for the ground and water to smooth noise, blended with a single short exposure for the sky, all 15 seconds at f/2 and ISO 3200, with the 20mm Sigma Art lens and Canon EOS Ra camera (with the Nikon-mount Sigma lens adapted to the EOS Ra with a Metabones F to RF adapter). LENR employed on all shots to reduce thermal noise this warm summer night.
