nebula

To capture the Great Nebula in Orion (M-42; NGC-1976) Tuesday night, Marty Murphy, AD, stacked 18 15-second images of the nebula using a 600-millimeter f/8 telephoto lens. The camera and lens were piggy-backed on a large telescope for tracking during the long exposures. This nebula is faintly visible to the naked eye in dark sky. It is situated in the middle of Orion’s dagger.
