Acquired from my amateur backyard observatory in Fremont, Michigan using a QHY11 Monochrome CCD/Takahashi E-180 using narrowband filters and captured over 5 nights, I started this project last year and it’s far from finished. Shown here is a Hubble Palette view of The Gamma Cygni Region covering 4.83 x 4.03 degrees of sky.
Total Integration Time 10 hours
The resolution is not the best either on Flickr or Facebook so I encourage you to view the image in this high resolution annotated view
nova.astrometry.net/annotated_full/1152351Prominent in this image is The Crescent Nebula NGC6888 over to the right, open cluster NGC 6874 top right, the sub-region Gamma Cygni Nebula IC1318A and part of the larger formation known as the Gamma Cygni Region (IC1318, or the Sadr Region). Just to the left of centre is open cluster IC1311.
Gamma Cygni/Sadr (bottom centre), the namesake star of the constellation of Cygnus the Swan. Very young for a star, a 12 million year old Supergiant and extremely bright. At a distance of 1,800 light-years, this young star easily outshines the vast majority of stars that are very close to the earth. In the study and classification of stars, Gamma Cygni served as an invaluable point of reference in contrast to other stars, allowing early astrophysicists the ability to develop an understanding of stellar evolution and a codified system of classifying all stars.
