NGC 2024 - Flame Nebula, Barnard 33 - Horse Head Nebula, and the bright star Alnitak that ionizes the Flame causing it to glow. Thicker patches of dust and gas in front of the nebula shows up as the dark patches. The center of the nebula contains a cluster of stars, many newly formed.
The Horse Head Nebula is a dark nebula that lies in front of an area of ionized hydrogen gas that is energized by the star Sigma Orionis. It also is a stellar nursery containing newly and currently forming stars.
Both are part of the Orion Molecular Cloud.
Cropped version as the bright stars in that area causes nice rainbow patterns in my camera. 80mm refractor and Asi071 camera.
