The Great Nebula in Orion (M42) spans about 24 light years across, and lies at a distance of approximately 1300 light years. It is the birthplace of young stars and at its core lies the trapezium.
This is an HDR composite image comprised of 3 different exposures at iso 800. 21-30 second exposures, 20-90 second exposures and 19-180 second exposures all taken on the same night.
Efforts have been made not to 'blow out" the trapezium. It is estimated that there are over 700 stars at various stages of star formation in this region. The distinctive reflection nebula dubbed the running man nebula lies to the left in the image.
