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.
Barnard 72 is a dark nebula located in the constellation of Ophiuchus. Often called the Snake Nebula, the thicker regions of gas and dust blot out the light from the background stars of the Milky Way Galaxy. Several other dark nebula are visible in the image.
Imaged with the ED80cft refractor and ZWO1600 mono camera.
Barnard 86 is a dark nebula located in the constellation of Sagittarius. The nebula is dense enough to block the background stars in this densely populated area. Also visible is the open cluster NGC 6520, which may be associated with the nebula.
Imaged with the RC10 and Atik 314l+ mono ccd.
