Here is an image of several nebulae around the star Alnitak (Zeta Orionis). Alnitak is the easternmost star in the Belt of Orion. Three prominent nebulae in this image are the Flame Nebula, the Horsehead Nebula, and IC 434. Several smaller reflection nebulae dot the area.

The Horsehead Nebula is a dark nebula, which is an opaque cloud of dust and gas. Located behind it is emission nebula IC 434. The Flame Nebula is being lit up by Alnitak and stars buried within the nebula.
Here is an image of this same area that I made using Sam Houston State University's Takahashi Epsilon-200:
