The Great Orion Nebula comprised of M42 and M43 with the Trapezium near the center.
Because of its high dynamic range, the Great Orion Nebula is difficult to capture with a single exposure duration. This is a high dynamic range image made by combining short exposures for the Trapezium and bright central portions of the nebula, longer exposures for the middle range of the nebula, and still longer exposures for the faint peripheral nebulosity and dust clouds.
