A portrait of emission nebulas and dark dust lanes in Cygnus around Deneb, including the North America Nebula NGC 7000 at upper left and the Gamma Cygni or Butterfly Nebula IC 1318 at lower right. I shot this with a waxing quarter Moon in the sky on November 21, 2020, using the red-sensitive Canon EOS Ra equipped with a clip-in Astronomik 12nm H-a filter to isolate just the deep red Hydrogen-alpha emission line, but resulting in a monochromatic image. This is a stack of 24 x 3-minutes at ISO 3200 with the 135mm Canon lens wide open at f/2. Star images toward the bottom are aberrated, I think due to the filter being slightly tipped in the camera body. For artistic effect I added a mild Orton Glow with Luminar 4 and then a blue tint and frame with Nik Collection SilverEFX Pro filter. Some of the tonal stretching was done with luminosity masks created with Lumenzia.
Emission nebulas in northern and central Cygnus, including the North America Nebula (NGC 7000) at lower left and the Gamma Cygni complex (IC 1318) at upper right. Deneb is the bright star at left, while Gamma Cygni itself is at upper right. However, the image works well turned 90° to portrait with Deneb at top. This is a stack of 8 x 2-minute exposures with the 200mm lens at f/2.8, and filter-modified Canon 5D MkII at ISO 1600, taken from home on May 30, 2017 as part of testing the Star Adventurer Mini tracker. All exposures tracked but not guided.
The complex of red emission and dark dusty nebulas in Cygnus, with the bright Cygnus starcloud at bottom and the North America Nebula at top. At the very top is the dark Funnel Cloud Nebula. At lower left are the arcs of the Veil Nebula. Below them is the large star cluster NGC 6940 in Vulpecula. At centre is the IC 1318 nebula, aka the Butterfly. This is a stack of 15 x 2-minute exposures with the Canon RF 28-70mm lens at 50mm and wide open at f/2, taken as part of testing the lens. The lens was shooting though a URTH Night broadband light pollution rejection filter to reduce the green airglow present this night in a shoot from home. The camera was the Canon Ra at ISO 1250, and was on the Star Adventurer Mini tracker. All stacking, alignment and blending with Photoshop 2021.
