The Great Orion Nebula
Photographed by Scott Davis on February 9, 2013
From Eastman Lake, California
Description:
The Great Orion Nebula, also known as M42, is one of the most beautiful objects in the sky, visible through binoculars and telescopes even from bright skies due to its brightness. This nebula also contains M43, which is the circular nebula just off the main nebula. Finally, to the right of the image is the Running Man Nebula, also known as NGC 1973, 1975, and 1977, a reflection nebula which seems to show the shadow of a man running through space.
