About this work
Horsehead Nebula (also known as Barnard 33 in emission nebula IC 434) is a dark nebula in the constellation Orion.
The image is a frame mosaic taken with 5 different filters, standard Red – Green – Blue with details enhanced with narrowband data of Hydrogen-alpha (Hα) and O III. The Hα was color-mapped to red and the O III to teal. So it is a representative color image consisting of over 900 minutes of exposure time.
