Sky Position

The Horsehead Nebula is a dark nebula of dust silhouetted against the glowing hydrogen emission of IC 434. The distinctive equine profile rises from a ridge of molecular cloud in the Orion constellation. This HOO narrowband image uses hydrogen-alpha data for the red channel and OIII for the blue-green, revealing the intricate filamentary structure of the emission nebula behind it.
