This is 1×2 mosaic of an extremely beautiful area (around M 42, the Orion Nebula) and often “visited” by astrophotographers around the world. NGC 2024 (also known as the Flame Nebula) is the nebula sitting on the left hand side of this mosaic. It is an emission nebula that is better imaged with Halpha. IC 434 (on the right) is a bright red emission nebula, with Barnard 33, a dark nebula (better known as the Horsehead Nebula)  superimposed in front of it, showing a seahorse head shape, more than a horse (but some people disagree). The blue-colored nebula just right off of center is NGC 2023, a reflection nebula with minor emission lanes (in red) that is aesthetically very nice, but often overlooked due to its spectacular neighbors.
