The queen of nebulae, Great Nebula in Orion or simply Messier 42 is a great and very beautifull nebula located in Orion constellation. It's visible with a naked eye even under suburban skies. It is a large diffuse (contains emission and reflection parts) nebula - star forming formation closest to earth (1344 +/- 20 light years from us). Estimated size of this object is about 24 light years across. IC 1977 "The Running Man Nebula" is located on the left from Orion's Nebula. The foto of this object was my dream since my initiation in area of astrophotography.
