The Horsehead Nebula, B33, below the Belt of Orion and the star Alnitak, along with the bright Flame Nebula, NGC 2024, to the left of Alnitak. Many other bright reflection nebulas populate the field, such as NGC 2023 just left of the Horsehead itself. The quintuple star system Sigma Orionis is right of the Horsehead. The dark Horsehead is set against the bright streak of the emission nebula IC 434.
