$65.00 $52.50

The Horsehead Nebula is located 1500 light years away in the Orion constellation. It is one of the most iconic features in our Milky Way and is widely photographed. It is a reflection nebula made up of obscuring gas in the shape of a horse’s head back illuminated by the red light emission from Hydrogen gas. The bright star to its left is the left most of the 3 Orion belt stars Alnitak. The nebula just below is the Flame Nebula, NGC 2024. The image was done using narrowband Hydrogen and Sulfur filters with the hydrogen emission in red in this image which is its natural color. Some people think that the horse head looks more like a skiier with his head ducked down.
