Messier 42, the magnificent Orion Nebula

Messier 42, the magnificent Orion Nebula, a favorite object in any amateur telescope, is usually portrayed in vivid, high contrast colors. While that looks spectacular, the reality is that one of our closest stellar nursery’s true colors are likely much more subdued. I have attempted to depict it in hues one might expect as seen in a large aperture telescope, showing the light pink emission regions and the bluish reflection veils surrounding the nebula’s core.
DETAILS: Astro Physics AP 155 Starfire shooting at f/5.2, though an IDAS LPS-V4 filter and a spectrally modified Canon EOS 6D Mrk II. Total exposure: 8 minutes at ISO 4000.
