The often-photographed (certainly by me) area of the North America Nebula, NGC 7000, near the bright star Deneb, which is in the frame at right, in Cygnus. The Pelican Nebula, IC 5067/70 is right of the North America, in the “Atlantic Ocean” so to speak. The nebulosity at bottom is the “Cygnus Arc,” IC 5068. The small patch of blue reflection nebulosity at top is IC 5076. The patches of dark nebulosity above the North America Nebula are B352 and B356. This is a stack and blend of: four exposures without a filter, each 8 minutes at ISO 800, and four exposures with an Optolong L-Enhance nebula filter to bring out the faintest nebulosity, each 16 minutes at ISO 1600. These are blended in with a Lighten mode. All were with the William Optics RedCat 51mm astrographic refractor at its native f/5 and Canon EOS Ra camera, the factory filter-modified camera capable of recording this type of hydrogen-alpha emitting nebulas. Guided with the ZWO ASIAir and ASI120MM guide camera, on the Astro-Physics Mach1 mount. Taken from home on a perfect summer night on August 15, 2020.
