Orion nebula(M42) and Running man nebula(NGC 1977)

Used a stock camera(Nikon D5600) with a very close spectral response similar to the human eye. Hydrogen emission nebulae actually appear pink due to H-alpha (red), H-beta (blue) and emission from other atoms, like oxygen and sulfur. Orange faint nebulosity is the dust clouds.
