This image shows the large area of Hydrogen-Alpha emmission nebulosity called Then North America Nebula due to it's rough similarity in shape to the North America continent. The large nebula cloud lies just east of the bright star Deneb in the constellation Cygnus, which is situated right along the summer Milkyway's inside band (towards the center of our galaxy, spiral arm) , this is responsible for the dense starfield surrounding the image frame. To the west of NGC 7000, is another semi large cloud of Hydrogen-Alpha emmission nebulosity called the Pelican Nebula (not shown in this frame), due to its shape looking like that of a Pelican's head and beak, these two nebula clouds are often imaged as a pair with very short focal length refractors and telephoto camera lens'. This image was captured from bortle yellow, VLM 6.0 skies, in Southern New Jersey at a field in the Pine Barrens Reserve called Coyle Field, a popular darksite location for imagers and visual observers within the NY and Philadelphia metro areas. The image data was captured with a modified/TEC cooled Canon 350xt DSLR, the final image is comprised of 10x480 second iso800 sub exposures, the primary imaging optics consisted of a C-80EDF F/6.25 FL=500mm, SV flattener, CLS-CCD eos clip lp filter, mounted on a EQ-G mount, and the mount was guided through the sub exposures using PHD software, with a side x side mounted Orion ST120 refractor and a DSI camera, the data was dark, flat and bias frame calibrated using MaximDL, and was then post processed using PS CS2
