The North America Nebula ... NGC 7000



The North America Nebula ... NGC 7000
Date: July 21, 2019
This is an emission nebula (which has a conspicuous resemblance to the North America Continent) in the constellation Cygnus the Swan and very near the bright star Deneb (Which is one of the 3 bright stars composing the 'Summer Triangle'). It is large, covering an area of more than four times the size of the full moon; but its surface brightness is low, so normally it cannot be seen with the unaided eye. It is about 1,600 light-years away. This is a 78-minute exposure. I had to toss an additional 40 minutes of data due to passing clouds contamination and the stacking software PixInsight tossed out an additional 19 frames (38 mnutes). I originally stacked the frames in Deep Sky Stacker but after stacking PI, I combined the two products using the image from PI as a 'Color' layer over the DSS image for the final image.
