Retour vers le pass\u00e9 – es captures datent de 2025…<\/p>\n

M82, aussi surnomm\u00e9e la galaxie du Cigare, est une galaxie spirale situ\u00e9e \u00e0 environ 12,5 millions d’al).
\nElle se situe dans la constellation de la Grande Ourse.
\nUn vaste complexe de filaments gazeux s’en \u00e9chappe.
\nLes bras spiraux n’ont \u00e9t\u00e9 rep\u00e9r\u00e9s qu’en 2005.<\/p>\n

M82 a \u00e9t\u00e9 d\u00e9couverte par l’astronome allemand Johann Bode en 1774.
\nElle est voisine de M81 (d\u00e9couverte aussi par Bode), une superbe galaxie spirale.<\/p>\n

La voici avec le VC200L (taille r\u00e9duite \u00e0 50%, qualit\u00e9 JPEG 75) :<\/p>\n

Les d\u00e9tails techniques :<\/p>\n

Vixen VC200L, diam\u00e8tre 200 mm, focale 1800 mm (F\/9)
\nCam\u00e9ra ASI294MCPro (4.63 microns), aimablement pr\u00eat\u00e9e par Alexandre Lhoest (merci !!)
\nR\u00e9solution 0.529 arcsec\/pixel
\nFiltres Optolong L et IDAS LPS2
\n20 images de 8 minutes, soit 2h40m de pose – c’est peu…<\/p>\n

Monture AP Mach1 guid\u00e9e.<\/p>\n

Capture avec MaxIm\/DL, 2 nuits seulement fin avril 2025, beaucoup de satellites.
\nTraitement dans PixInsight.<\/p>\n

M82 est membre du groupe de galxies de M81, qui compte pr\u00e8s d’une quarantaine de galaxies.<\/p>\n
