This project represents my first set of Ha lights with the Baader HighSpeed f/2 filter and practically the first capture with the large HyperStar 11 v4 telescope.
|It was made on February 4 2021, at a temperature of -12 ° degrees but with perfectly clear skies.
The color capture was made using a SW Ed80 telescope and a Color camera, on March 3 2021, through the clouds and with Orion located at 25 °degrees above the Bucharest area (SQML 18).
The color signal input was very weak, the processing being a real challenge, but I managed to bring a little color in this exposure.
The Horsehead Nebula, officially known as Barnard 33 (the object IC 434 designates the last emissive nebula in the background), is an obscure nebula located in the constellation Orion, below Zeta Orionis (Alnitak), the easternmost star in the belt of the constellation Orion.
This nebula, located 1,500 light-years away, was first discovered in 1888 by the American Williamina Fleming, on a photographic plate taken at the Harvard College Observatory.
Objects:
Barnard 33, IC 432, IC434, NGC 2023, NGC 2024, Alnitak Star ζOriThe Horsehead Nebula is part of a large dark molecular cloud that is also known as Barnard 33.
The Horsehead Nebula is easily recognizable by its horsehead shape, which gave it its name.
The darkness of the horse's head is caused by the presence of a dense cloud of gas and dust.
The latter strongly absorbs the visible radiation emitted by the ionized gas in the background.
At the base of the head are young stars in formation.
Apparent magnitude Barnard 33: 6.8
Distance to Barnard 33: 1375 light years
Apparent magnitude (V) : 6.8
IC 434 - bright emission nebula in the constellation OrionBehind The Horse Nebula is hydrogen, which, ionized by the nearby bright star, Sigma Orionis, turns red.
Distance to IC434: 1500 light years
Apparent magnitude (V) : 7.3
NGC 2023 - is an emission and reflection nebula
Distance to NGC 2023: 1300 light years
NGC 2024 - Flame Nebula - is an emission nebula
The bright star Alnitak (ζ Ori), the easternmost star in the Belt of Orion, appears very close to the Flame Nebula in the sky. But the star and nebula are not physically associated with one another. The Flame Nebula contains a young cluster of stars which includes at least one hot, luminous O-type star labeled IRS 2b.[2] The dense gas and dust in the foreground of the nebula heavily obscures the star cluster inside the nebula, making studies at infrared wavelengths most useful.
Distance to
NGC 2024: 1350 light years
Apparent magnitude (V) : 10
IC 432 - is a Reflection Nebula
Clear sky !
