Salut,<\/p>\n

\u00e0 ne pas confondre avec une voisine la jelly fish nebula.
\nPk205+14.1 se trouve dans les G\u00e9meaux \u00e0 8\u00b0 au nord de Procyon. C’est une vieille n\u00e9buleuse plan\u00e9taire qui se trouve \u00e0 1500 a.l.<\/p>\n

Images captur\u00e9es ce d\u00e9but de nuit profitant d’une trou\u00e9e dans les nuages. Ciel laiteux malgr\u00e9 tout, cela n’a pas \u00e9t\u00e9 \u00e9vident \u00e0 traiter.<\/p>\n

Cela aurait \u00e9t\u00e9 sympa d’avoir plus de poses mais la m\u00e9t\u00e9o en a d\u00e9cid\u00e9 autrement.<\/p>\n

Traitement sous PI mais je ne vais pas d\u00e9velopper ici. Si cela int\u00e9resse quelqu’un…<\/p>\n
