Description

Dark nebulae are clouds of dust in space that obscure the stars behind them.  Emission nebulae are clouds of glowing ionized gas.  Reflection nebulae do not shine by their own light, but are visible because they reflect the light of nearby stars.  B33 (Baranrd 33) or the Horsehead Nebula is perhaps the best known example of a dark nebula.

The IC434 complex which includes B33 and other deep sky objects is located in the constellation Orion, just below the bright star Alnitak, the left most star in Orion's famous belt.

This is a good example of Jimmy's layering techniques used to process a difficult object.
