A famous, indeed iconic nebula in the constellation Orion, The Horsehead was not even discovered until 1888 with the advent of astro photography. It is very faint to see visually with a telescope.
The image above was captured with my TEC 140 refractor and Atik 460 CCD camera with Astrodon RGB and Ha(3nm) filters. It contains a total of 120 minutes of Ha data and 45 minutes each of RGB data, everything binned 1×1 with 5 minutes exposures.
