NGC 2070, the "Tarantula Nebula"
Natural color composition from the emission of ionized elements, R=80%Hydrogen+20%Sulfur, G=100%Oxygen and B=85%Oxygen+15%Hydrogen to compensate otherwise missing H-beta emission.
This composition is very close to a visual spectrum.
Tarantula nebula, NGC 2070, also known as 30 Doradus, is an ionized Hydrogen region in the Large Magellanic cloud, visible in southern hemisphere. Distance from Earth is about 160.000 light years.
