This is a portion of the North American Nebula, also designated as NGC7000 and Caldwell 20. It is an emmision nebula, a large region of interstellar gas and dust, not far from the easily visible star, Deneb, and about 2500 light years away from your backyard. Its full size in the sky is stunning - over 10 times the area of the full moon, and 140 light years across. My image, taken with a 430mm focal length widefield refractor which when paired with my camera covers a ~2.5 degree Field of View of the sky on the wide dimension, only captures about 1/2 of the nebula at most. The nebula is ionized by a hot star, causing the Ha emmision. The dense gaseous area in the lower left is called the Cygnus Wall - although to me it looks like the horns on a gaesous beast flying through interstellar space - like an evil version of the white dragon from the movie The Never Ending Story. The story behind the capture.......On another night while waiting for Andromeda Galaxy to come over my treeline in the backyard, I decided to do just pick a target, this target, and image for just a couple of hours. I also accidentally rotated the camera after the imaging session so was not able to take full calibration images (which have to be taken in the exact configuration and orientation from which the primary target was imaged). However, despite the low exposure time, and my calibration snafus in the post processing of this after-thought of an imaging session, the beauty of the nebula was really mesmorizing to me. This is a narrowband image capturing H-alpha and O-III. In the image "stretch" (post processing the pixel histogram in two image processing SW packages), I brought out a bit more of the blue/green in the middle area of the nebula than the native Ha-image results, although if I was processing the image in purist terms, it would be entirely red from the Ha. I very much look forward to revisiting this target next year with much more exposure time and seeing what detail can be seen from my Bortle X backyard. Hope you enjoy!
