BARNARD 33 - THE HORSE HEAD NEBULA. Located approximately 1,500 light years away in the constellation Orion. This dark nebula is next to impossible to see visually with a telescope. The red glow behind is the emission nebula IC 434 which is glowing hydrogen gas fluoresced by ultraviolet radiation from the star Sigma Orionis. In the bottom left corner is the reflection nebula NGC 2023.

Imaged at Tres Placitas Observatory Santa Fe, NM February 2003
