Jupiter (brightest), Saturn (to the left), and the Milky Way over the Saskatchewan River and the area of Howse Pass, on July 26, 2020. Mount Cephren is at left; the scene is framed to include Cephren. The nebulas and star clouds of the galactic centre area at right show up well on this very clear night. The bright Small Sagittarius Starcloud, aka M24, is most obvious, flanked by the star clusters M23 and M25 to the side, and the nebulas M17 and M16 above, and M8 and M20 below. The fuzzy globular cluster M22 is to the left of the large Lagoon Nebula, M8. Green airglow tints the sky. This is an exposure blend of a stack of 4 x 2-minute untracked exposures for the ground at ISO 1600 (exposed long to bring out ground details), with 2 x 1-minute tracked and stacked exposures at ISO 3200 for the sky. Shot from the Howse Pass Viewpoint area off the Icefields Parkway at Saskatchewan River Crossing. The camera was on the iOptron SkyGuider Pro tracker. For the ground shots I simply turned the tracker motor off. All with the 35mm Canon lens at f/2.8 and Canon EOS Ra, a filter-modified camera. Topaz Sharpen AI applied to the ground; Topaz DeNoise AI applied to the sky. In camera LENR employed on all shots on this warm night. An Orton soft glow effect added to the sky with Luminar Flex plug-in.
Comet NEOWISE (C/2020 F3) on July 26, 2020 from Saskatchewan River Crossing in Banff National Park, Alberta. The comet is just about to set behind Mount Wilson, the iconic peak in the area. A meteor appears at top in the image framed to include the Big Dipper and the constellation of Ursa Major. While the comet was fading, its blue ion and white dust tails still show up well. It was from near here that scientist and explorer James Hector, member of the 1858-59 Palliser Expediton, observed Comet Donati on September 10, 1858 as they made their way up the valleys of the Bow, Mistaya, Howse and Saskatchewan Rivers, as part of a British scientific expedition to map the area and much of southern Alberta. This is an exposure blend of a stack of 4 x 2-minute untracked exposures for the ground at ISO 800 (exposed long to bring out ground details), with 3 x 30-second tracked and stacked exposures at ISO 1600 for the sky. I shot short exposures for the sky to catch the comet before it set. The meteor was on one frame of the sky stack layered and blended in separately. The camera was on the iOptron SkyGuider Pro tracker. For the ground shots I simply turned the tracker motor off. All with the 35mm Canon lens at f/2.8 and Canon EOS Ra. Topaz Sharpen AI applied to the ground. In camera LENR employed on all shots on this warm night. Shot from the parking lot of the Howse Pass Viewpoint area off the Icefields Parkway.

Mount Wilson at right is lit in part by the setting Moon out of sight behind the foreground hill and by lingering summer twilight lighting the horizon over the Saskatchewan River valley at centre. This is an exposure blend of a stack of 4 x 2-minute untracked exposures for the ground at ISO 200, with 3 x 1-minute tracked and stacked exposures at ISO 400 for the sky. Stacking the images smooths noise. Tracking the sky prevents star trailing in the long exposures needed to reveal lots of stars and the fading comet well. The camera was on the iOptron SkyGuider Pro tracker. For the ground shots I simply turned the tracker motor off. All with the 35mm Canon Art lens at f/2.8 and Canon EOS Ra. Topaz Sharpen AI applied to the ground. In camera LENR employed on all shots on this warm night.
