Narrowband Horsehead region
This is a narrowband image of the Horsehead nebula (B33) region in Orion taken with the Tzec Maun telescope in Mayhill. The "Horsehead" is actually a cold, thick, dark gas that is blocking the light from the bright (emission) nebula behind it. Hydrogen is indicated with red, sulfur is in green (yellow is a combination of hydrogen and sulfur) and Blue is Oxygen. The dats was collected back in January 2011 (3.5 hours worth) and processed by Steve. Thanks Steve !
