Notes:
|
The Horsehead nebula is a relatively small dark nebula comprised of mostly dust illuminated against the faint glow of emission nebula (excited hydrogen) IC 434. This whole region is part of the Orion molecular cloud, a rich star forming region, which also includes the Orion Nebula (M42) |
| The
Flame Nebula (NGC 2024) is a bright emission nebula which is aptly
named although it also reminds me of a Fall Maple Leaf.
The very bright
star left of center is Alnitak or Zeta Orionis, the third
"belt star" in the distinctive Orion constellation.
