Cygnus Nebulosity Bright and Dark (RF135mm RMod).jpg
This is a framing of the rich region of bright emission and dark dusty nebulas in northern and central Cygnus, including the North America Nebula (NGC 7000) at left and the Gamma Cygni or Butterfly Nebula (IC 1318) at lower right.
Beside the North America Nebula is the Pelican Nebula (IC 5070). In the lower right corner is the small Crescent Nebula (NGC 6888). Below the bright star Deneb is the dark region known as the Northern Coal Sack. The star cluster at upper right is NGC 6866, and at top is the colorful triple star Omicron Cygni. The field is filled wiith wreaths of fainter nebulosity, some from the Sharpless Catalogue, others from the even more obscure DWB (Dickel-Wendker-Bieritz) Catalogue. A small blue-white reflection nebula from the van den Burgh Catalague (vbB131/2) is near centre. The distinct elongated dark nebula at lower right is Barnard 145.
Technical:
Taken on a very fine night, August 7, 2024, at the Saskatchewan Summer Star Party in the Cypress Hills. This is a stack of 27 x 1-minute exposures with the Canon RF135mm lens at f/2 and the filter-modified Canon R at ISO 1600. The lens had an URTH Night Sky filter on it, a broadband light pollution reduction filter, to help suppress natural green airglow and improve contrast. The camera was tracked on the MSM Nomad tracker, with no guiding. Star glows added with a mild application of a layer from a single exposure through a Tiffen Double Fog 3 filter.
