M81 (NGC 3031 \/ Galaxie de BODE) est une galaxie spirale situ\u00e9e dans la constellation de la Grande Ourse \u00e0 environ 12 millions d’ann\u00e9es-lumi\u00e8re de la Voie lact\u00e9e.
\nElle est de dimensions inf\u00e9rieures \u00e0 notre Voie Lact\u00e9e, son diam\u00e8tre \u00e9tant estim\u00e9 \u00e0 environ 87 000 ann\u00e9es-lumi\u00e8re (contre au moins 100 000 pour notre galaxie).
\nElle est souvent photographi\u00e9e avec son compagnon M82, distant d’\u00e0 peine 120 000 ann\u00e9es-lumi\u00e8re, et elles comptent parmi les galaxies les plus proches de la n\u00f4tre.
\nM81 pr\u00e9sente \u00e9galement de belles r\u00e9gions de formation d\u2019\u00e9toiles dans ses bras spiraux, signe d\u2019une activit\u00e9 de formation stellaire assez soutenue.<\/p>\n

Voici donc ce que j’ai pu sortir pour M81. 20 x R – 20 x G – 25 x B – 36 x L. Poses de 300 sec sous des cieux pas top, et avec une lune entre 50% et 60%.
\nC’est pas le meilleur, j’ai du pousser un peu dans PIX et PS.
\nMatos: Skywatcher 250\/1200 – AZEQ6 – ASI 1600 MM Pro
\nD\u00e8s que ce sera possible, j’y ajouterai un peu plus de RGB et un peu de Ha.<\/p>\n
