Description

The 'Great Orion Nebula', M42 or NGC1976, is located in the sword of Orion and is one of the brightest nebula in the sky, and perhaps the best known. It is a young star formation region with very hot high-UV stars ionising and 'lighting' the nebula.The brightness of these young stars make this an astrophotography challenge as the central regions are very bright in comparison to the tenous outer nebula and over exposure becomes a problem. High Dynamic Range (HDR) techniques must be used to produce an image with a 'flattened' brightness range, more akin to the way the human eye perceives a wide range of brightness.
