Description

The Great Orion Nebula, M 42, is always a challenge to image processing due to its high dynamic range. In this example, luminance frames were taken with 10, 30 and 120 seconds exposure time, the unbinned colors were taken with 120 seconds exposure time each. For luminance processing, HDR composition and HDR wavelets have been applied.
