North America Nebula: NGC 7000
Combined the images I took back in June with a additional set of Sulphur and Oxygen filters and with updated processing techniques....
"The North America Nebula, designated NGC 7000, is a vibrant emission nebula resembling the continent of North America in shape, located about 1,600 light years from Earth in the constellation Cygnus. Spanning about 100 light years in diameter, this nebula is illuminated by the bright star Deneb, one of the farthest stars visible to the naked eye, which energizes the nebula's hydrogen gas causing it to glow with a red hue.
The dark regions within the North America Nebula, particularly prominent in the "Gulf of Mexico" area, play a critical role in the nebula's visual appearance and its astrophysical dynamics. These dark clouds, composed of dense, cold dust and gas, absorb much of the light from the background nebular glow and from stars forming within them. These areas are thought to be active sites of star formation, where the dense materials are collapsing to form new stars." --synthesized from multiple sources.
