Description
This is a 6-panel mosaic capture the North America Nebula (on the left) and Pelican Nebula (on the right: looks a bit like a pterodactyl). My family and I affectionately refer to the two stars + nebulosity between them as the Deadpool Nebula--see if you can find it! :-) The photo combines 30 hours of imaging, including 12 hours of ionized hydrogen-alpha and oxygen, and 18 hours of ionized sulfur and hydrogen-beta. All imaging was in my Indiana backyard on a 4.5 refractor.
This photo is near the Summer Triangle: 3 bright summer stars consisting of Deneb, Vega, and Altair. This field of view is very close to Deneb, and the bright pink ionized hydrogen can be seen even in short exposures with regular cameras.
This not a "real-color" image: I imaged ionized sulfur ([SII]) and colored it a deep red, ionized hydrogen-alpha (Ha) as gold, and I blended ionized oxygen ([OIII]) and hydrogen-beta (Hb) as deep blue.
