La N\u00e9buleuse de la petite Rosette, SH2-170, en r\u00e9f\u00e9rence \u00e0 sa grande s\u0153ur la n\u00e9buleuse de la rosette qui lui ressemble, est localis\u00e9e dans la constellation de Cassiop\u00e9e \u00e0 environ 7’500 ann\u00e9es-lumi\u00e8re du syst\u00e8me solaire.
\nMais d’autre infos la situe plus loin….
\nIl semble qu’elle soit un peu moins photographi\u00e9e. Peu de donn\u00e9es sur le NET pour cet objet. M\u00eame pas un WIKI…\u00e0 ma connaissance. C’est une n\u00e9buleuse \u00e0 \u00e9mission.
\nVoici ce que j’ai pu trouver :
\nL’\u00e9toile qui ionise la zone est AG+64 1262 une \u00e9toile de type spectral O, la masse de gaz ionis\u00e9 a \u00e9t\u00e9 \u00e9valu\u00e9e en 2004 \u00e0 350 millions de masses solaire sur un rayon de 32 A.L., pour une r\u00e9gion gazeuse totale d’environ 1000 millions de masses solaire.<\/p>\n

Technique :
\nEn couleurs \u00ab\u00a0naturelles\u00a0\u00bb, \u00e9tant donn\u00e9 que Ha et SII sont vers le rouge, le tout serait comme un gros nuage rouge\u00e2tre. Peu de OIII.
\nJe la pr\u00e9f\u00e8re en \u00e9dition SHO + RGB…:-)…Les \u00e9toiles en RGB.
\nPrises de vues en Ao\u00fbt et septembre 2022<\/p>\n

Ha = 57 x 300sec = 4h 3\/4
\nSII = 30 x 300 sec = 2h 1\/2
\nOIII = 34 x300sec = 2h 3\/4
\nR = 20 x 120sec = 1h
\nG = 20 x120sec = 1h
\nB = 20 x120sec = 1h
\ntotal 13h<\/p>\n
