The Horsehead Nebula

Dark Nebula in Orion

Uploaded 12/30/2001

Superimposed on IC434 is the famous dark nebula, the Horsehead, which resembles a side view of its namesake. This object is difficult to photograph due to its faintness and proximity to Zeta Orionis off to the left in this image with north in that direction. This is one of the very few nebula in the entire sky that is best seen with the Hbeta filter visually. Seeing was very poor and the stars are a bit enlarged here.
