Appel\u00e9e aussi n\u00e9buleuse du Cygne, du Fer \u00e0 Cheval ou du Homard, bien visible dans le Sagittaire et distante de 5000 A.L.
\nCaptur\u00e9e ici avec un boitier Canon 20Da (modifi\u00e9 \u00ab\u00a0astro\u00a0\u00bb d’origine) au foyer du T255 de La SAL \u00e0 Nandrin en juillet dernier sous un ciel favorable. Filtre Neodyme, guidage perfectible et turbulence assez \u00e9lev\u00e9e…
\nAddition de 4x 4min \u00e0 800iso et retrait d’un seul dark sous Iris.
\nLe 20Da est un peu moins sensible dans le rouge profond qu’un boitier modifi\u00e9 soi-m\u00eame (par retrait du filtre ou son remplacement par le filtre ir-cut d\u00e9di\u00e9 Baader) mais semble donner des couleurs plus nuanc\u00e9es.
