Bonjour,
\nla r\u00e9gion d\u2019Ophiuchus regorge de n\u00e9bulosit\u00e9s sombres, dont les plus connues sont certainement les n\u00e9buleuses du Serpent (B72) et de la Pipe (B59, B72, B77 et B78).
\nVoici une photo de la partie nord de la Pipe (B77) et du Serpent, qui couvre un champ de 3.7\u00b0x2.5\u00b0.
\nB68, la tache la plus sombre en dessous du serpent est un globule de Bok, distant de 500 ann\u00e9es-lumi\u00e8re du Soleil. Il fait \u00bd al pour pr\u00e8s de 2 masses solaire. Au d\u00e9veloppement, je me suis rendu compte que j\u2019avais aussi pris dans\u00a0mes \u00ab\u00a0filets\u00a0\u00bb une n\u00e9buleuse plan\u00e9taire\u00a0: NGC6369 ou n\u00e9buleuse du petit fant\u00f4me (28\u201d d\u2019arc apparent), visible sous la forme d\u2019un petit anneau r\u00e9gulier. <\/p>\n

\"\"<\/a><\/p>\n

L\u2019image annot\u00e9e ci-dessous identifie NGC6369 ainsi que les n\u00e9bulosit\u00e9s sombres reprises dans le c\u00e9l\u00e8bre catalogue de Barnard (source\u00a0: Atlas Photographique d\u2019Edward E. Barnard https:\/\/exhibit-archive.library.gatech.edu\/barnard\/ ). A noter que B75 ne s\u2019y trouve pas parce que cette n\u00e9bulosit\u00e9 est plus au nord de B261. <\/p>\n

Photos prises le 11\/8\/2018 pr\u00e8s d\u2019Arvieux en Queyras (France).
\nLunette 80APO + Canon 450D d\u00e9filtr\u00e9 et filtre LPS. 70 min en sub de 120s non guid\u00e9, \u00e0 1600iso. Traitement PixInsight et Affinity, image r\u00e9duite d\u2019un quart.<\/p>\n\n\n
