Horsehead and Flame Nebula

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.

Exposure: LRGB, 20 x 600sec + (18,18,18) x 300sec Date: 2016-2-11…17
Setup: Takahashi FSQ106 EDXIII with QSI 683WSG-8 Site: Deep Sky West Observatory, NM, USA
