M1<\/strong>. La c\u00e9l\u00e8bre n\u00e9buleuse du Crabe est le reste de l’explosion en supernova d’une \u00e9toile. Il ne s’agit donc pas \u00e0 proprement parler d’une n\u00e9buleuse plan\u00e9taire. Cette image est le r\u00e9sultat de l’addition de 20 poses avec filtre rouge plus 20 poses avec filtre vert et 25 poses avec filtre bleu, toutes de 30 secondes en binning 3×3. Pour la luminance, j’ai additionn\u00e9 50 poses de 30 secondes prises en binning 2×2. J’ai utilis\u00e9 le binning 3×3 car les rafales de vent et la tr\u00e8s forte turbulence d\u00e9gradaient d\u00e9j\u00e0 fortement la r\u00e9solution. Traitement sous CCDSoft , assemblage LRGB avec Photoshop Elements 2 et finition sous PSP.
\nNGC2438<\/strong>. Cette petite n\u00e9buleuse plan\u00e9taire se trouve dans l’amas ouvert M46. Cette vue en mode RGB est le r\u00e9sultat de l’addition de 26 poses dans le rouge et dans le vert plus 32 poses dans le bleu, toutes de 30 secondes en binning 2×2. Traitement avec CCDSoft et CCDops pour le DDP, finition sous PSP. La turbulence tr\u00e8s forte pendant les prises de vue a s\u00e9rieusement d\u00e9grad\u00e9 la r\u00e9solution.
\nLes photos pr\u00e9sent\u00e9es ici ont \u00e9t\u00e9 prises \u00e0 La Fosse ce samedi 15 janvier avec la ST10XME sur le CG11 \u00e0 F\/D 6,3. <\/p>\n
