A famous scenery, the Horsehead Nebula (B33), the Flame Nebula (NGC2024), and the blue supergiant star Alnitak the east-most star in the Belt of Orion surrounded by more subtle nebulosity.
This is an LRGB composite image using a total of around 8 hours of data taken at the Deep Sky West observatory. The processing was pretty basic, the only trick was to use short-exposure data in a HDRCombination for the luminance channel to reduce the glare and size of the bright blue stars.
