Sh2-157 est un bel ensemble tr\u00e8s \u00e9quilibr\u00e9 en hydrog\u00e8ne II comme en Oxyg\u00e8ne III, cela faisait longtemps que je voulais photographier cette zone du ciel. Voil\u00e0 qui est fait.<\/p>\n

Appel\u00e9e \u00e9galement the lobster claw Nebulae, Sh2-157 est une n\u00e9buleuse \u00e0 \u00e9mission dans la constellation de cassiop\u00e9e et C\u00e9ph\u00e9e \u00e0 une distance de 8000 ann\u00e9es lumi\u00e8res.<\/p>\n

Voici une description d\u00e9taill\u00e9e de l’image o\u00f9 vous reconnaitrez les objets principaux de l’image.<\/p>\n

L’arc du haut d\u00e9clin\u00e9 en SG13 et SG14 serait la cons\u00e9quence d’une \u00e9toile Wolf Rayet qui appartient \u00e0 l’amas ouvert Markarian 50 ou Ba3.<\/p>\n

\"sh2-157-hao3bluerv-o3_blue6-aladin\"2 articles int\u00e9ressants qui date de 1985 et 2004 vous en diront un peu plus long sur cet ensemble complexe.<\/p>\n
