Cygnus Landscape Panorama (RF135mm Ra).jpg
This is a panorama along the Milky Way framing the nebulosity and star clouds in Cygnus the Swan, taking in about 40° along the northern Milky Way.
At centre is the complex of nebulosity around the star Gamma Cygni, aka Sadr, catalogued as IC 1318. At left and below bright blue Deneb is the North America Nebula (NGC 7000) and its companion Pelican Nebula (IC 5070). At far left at top is the dark nebula known as the Funnel Cloud, or Le Gentil 3. The dark Northern Coal Sack region is between Deneb and Sadr.
The small Crescent Nebula, NGC 6888, is right of centre, while the Tulip Nebula, Sharpless 2-101, is the small patch of red to the right of it. The distinct dark nebula just above the line between the Crescent and Tulip is Barnard 145. The bright Cygnus Starcloud along the neck of the Swan is at right, with dark nebulas and interstellar dust yellowing its tint. The Milky Way and the dark sky background exhibits subtle colour variations due to absorbing dust, and the dark nebulas show differing levels of density and darkness.
This is a panorama of 4 segments, each a stack of 10 x 1-minute exposures with the Canon RF135mm lens at f/2 (stopped down just 1/3 of a stop from wide open) on the Canon Ra factory-modified H-alpha sensitive camera at ISO 800. The camera was in landscape orientation along the Milky Way. The lens had a front 82mm broadband light pollution reduction filter on it, the URTH Night filter, to help emphasize the nebulosity and improve contrast. But no narrowband filters were employed here. Star reduction was with RC-Astro StarShrink. Nebulosity contrast was enhanced with luminosity masks created with Lumenzia extension panel, and with Nebula filter action in the Photokemi Actions set. High Pass sharpen filgter and ON1 Dynamic Contrast filter helped boost fine contrast structures.
Taken from home in southern Alberta at latitude 51° N on May 12/13, 2023, during the brief hours of darkness this spring night. Even so the sky was not fully dark
