Barnard 33 - The horsehead Nebula [edit: better process]

altresì nota come nebulosa oscura "testa di cavallo" e IC 434, NGC 2023 NGC 2024

è leggermente croppata per via dell'aggiunta di 3 scatti in h-alpha fatti la scorsa settimana a Saint-barthèlemy

 

"The Horsehead Nebula (also known as Barnard 33 in emission nebula IC 434) is a dark nebula in the constellation Orion.[1] The nebula is located just to the south of the star Alnitak, which is farthest east on Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex. The Horsehead Nebula is approximately 1500 light years from Earth. It is one of the most identifiable nebulae because of the shape of its swirling cloud of dark dust and gases, which is similar to that of a horse's head when viewed from Earth. " fonte wiki
