North America Nebula – NGC7000
North America Nebula – NGC7000
NGC7000 North American Nebula, a huge system in cygnus and it took me 8 nights of shooting to get here with about 40 hours of exposures in a 2×2 Mosaic. It’s a diffuse nebula in the milky way band and first seen 1786, later cataloged. It’s about 2500 light years away… observing what left in 500bc. To put in perspective, its about the size of a dozen full moons when you view the sky.
