Heaven and Hell
bright nebulae and dark clouds in the heart of the North America Nebula
The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus. The remarkable shape of the nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico.
The portion of the nebula resembling Mexico and Central America is known as the Cygnus Wall. This region exhibits the most concentrated star Formation. The Cygnus Wall located about 1,500 light-years away from Earth and spans about 20 light-years across the universe.
I´ve made this short session of capturing photons from the Cygnus Wall during our holiday in Hungary in the backyard of my parents near the Lake Balaton in July 2018. I had only two short summer nights for imaging: the first for the luminance and color data (about 42 minutes) and a second night for the narrowband H-alpha channel (about 100 minutes). It was also a test for my new automated focusing system and off-axis guidance. The post-processing was done in two stages: first a monochrome, H-alpha image with removed stars to show the beautiful morphology of the bright dusty regions surrounded by gloomy dark clouds. In the second-stage I added this image to the LRGB data to show the rich star formation field in a more natural way.
