IC 1795 \u2013 N\u00e9buleuse de la t\u00eate de poisson<\/p>\n

Prise sur une p\u00e9riode allant de Mars \u00e0 Septembre de cette ann\u00e9e, cette n\u00e9buleuse \u00e0 \u00e9mission m\u2019a quand m\u00eame donn\u00e9 un peu de fil \u00e0 retordre. Les conditions m\u00e9t\u00e9o n\u2019ont pas toujours \u00e9t\u00e9 top.<\/p>\n

N\u00e9anmoins, j\u2019ai malgr\u00e9 tout pu tirer le portrait de cet objet situ\u00e9 dans la constellation de Cassiop\u00e9e et distante d\u2019environ 6000 AL, et qui comprend un ensemble de zones de gaz luminescents et des nuages de poussi\u00e8res . Elle se trouve juste \u00e0 cot\u00e9 de la n\u00e9buleuse du c\u0153ur, et couvre un champ d\u2019environ 20 minutes d\u2019arc ce qui correspond \u00e0 \u00b1 70 ann\u00e9es lumi\u00e8re (d\u2019apr\u00e8s la litt\u00e9rature).<\/p>\n

N\u00e9buleuse visible toute l\u2019ann\u00e9e, ceci permet donc d\u2019y revenir souvent. Certains la photographient pendant des dizaines d\u2019heures et obtiennent de vrais bons clich\u00e9s\u00a0.
\nMoi j\u2019y ai consacr\u00e9 environ 23 heures de prises de vues. Plus en Ha. La lune semblait polluer quelque peu en OIII et SII.
\nJ\u2019ai des poses de 180 sec quand le ciel \u00e9tait trop clair, et 300 sec pour de meilleures conditions.<\/p>\n

Il me faut encore r\u00e9gler mon probl\u00e8me de halo autour des \u00e9toiles. Le \u00ab\u00a0star mask\u00a0\u00bb dans PIX ne couvre pas toute l\u2019\u00e9toile et cela alt\u00e8re quelque peu la nettet\u00e9 de celle-ci.
\nOn apprend en continu dans ce hobby\u2026\u00a0:-)\u2026
\nMalgr\u00e9 cela le r\u00e9sultat n\u2019est pas trop mal pour l\u00a0\u2018amateur que je suis\u2026<\/p>\n
