\"outters-nicolas\"Pas facile ce cadrage quand on sait que la n\u00e9buleuse de la b\u00e9b\u00e8te est rattach\u00e9e \u00e0 celle du coeur.
\nMais j’ai quand m\u00eame voulu mettre en valeur cette r\u00e9gion \u00e0 droite de IC1795 tout en cadrant le centre d’IC1805.<\/p>\n<\/div>

IC 1795<\/b> est une n\u00e9buleuse en \u00e9mission<\/a> situ\u00e9e \u00e0 environ 6\u00a0000 ann\u00e9es-lumi\u00e8re<\/a> dans la constellation de Cassiop\u00e9e<\/a>. Elle couvre un champ d’environ 20 minutes d’arc<\/a>, ce qui correspond approximativement \u00e0 70 ann\u00e9es-lumi\u00e8re1<\/a><\/sup>.<\/p>\n

Proche du double amas de Pers\u00e9e<\/a> et de la n\u00e9buleuse du C\u0153ur<\/a>. \u00c0 environ 6000 ann\u00e9es-lumi\u00e8re de nous, ce complexe s\u2019\u00e9tend \u00e0 travers le bras de Pers\u00e9e de notre Galaxie, la Voie lact\u00e9e. Cette image couvre un champ de 70 ann\u00e9es-lumi\u00e8re de long.<\/p>\n

Elle est facile \u00e0 voir et se trouve dans un environnement tr\u00e8s riche avec IC 1805 et IC 1848, ainsi que de nombreux amas ouverts.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n
