Object Information                                            Imaging Details

The Horsehead Nebula is a dark nebula that resides in front of a vast diffuse (emission) nebula in Orion. Dark nebula are made of the same gas and dust that comprise emission and reflection nebula; however, there are no stars near the dark nebula to cause it to emit or reflect light.

The Horsehead Nebula is a tough object to see even in larger scopes unless an appropriate nebular filter (e.g. hydrogen-beta) is used.
