In Cygnus star formation extended H-II gas region and dark clouds of dust are found with long exposure astrophotographs. H-II is the ionized hydrogen gas, which emits red light at 656,3 nm in the visible range of light. Dust in front of an H-II region forms two of the famous formations seen in the night sky. Their common names are North America Nebula and Pelican Nebula. Catalog object identifiers of the two nebula are known as NGC 7000 and IC 5070, respectively. Both are located close to the brightest star α Cygni in the Cygnus star formation. α Cygni is the bright blue star located in the right side of my picture. This star is an evolved supergiant star with spectral type A2Ia. The image has been taken from the private observatory of my friend Thomas in Austria.
