NGC 7000 North America Pelican Nebulae SHO 2019

North America and Pelican Nebulae, SHO, 2019


1,500 light-years away, the famous North America and Pelican nebulae in a star forming region in Cygnus. Probably the most celebrated summer Northern Hemisphere nebulae for all the astrophotographers. An integration of Hydrogen-α, Oxygen III and Sulfur II data that I collected during the short and bright nights of June of 2019.
