\"outters-nicolas\"La derni\u00e8re image depuis chez moi \u00e0 Orange avec le T\u00e9lescope Rcos12″ et ses 2,8 m de focale.
\nLe tout a \u00e9t\u00e9 imag\u00e9 en bining 2×2 car la FWHM ne valait pas le coup de sur-\u00e9chantillonner \u00e0 0,6 arc sec par pixel, j’ai donc pr\u00e9f\u00e9r\u00e9 rester \u00e0 1,2 et la CCD me laisse encore 4 millions de pixels ce qui est ma foi tr\u00e8s confortable \"\"
\nVdb130 ( je n’ai pas trouv\u00e9 d’autres appellations) est bourr\u00e9e de petites choses sympa et peu vues \u00e0 cette focale l\u00e0, les d\u00e9tails sur les bandes de poussi\u00e8res laissent sans voie, en tout cas pour moi. Je vous laisse regarder l’image m\u00eame si, au niveau esth\u00e9tique, elle peut laisser perplexe, il n’en est pas moins qu’elle refoule de d\u00e9tails surtout sur la partie en haut \u00e0 gauche.
\nLa pose est de 26h20 en binning 2×2, je vous laisse calculer l’\u00e9quivalent en binning 1×1 ! \u00e0 F9 il ne faut pas \u00eatre press\u00e9<\/p>\n<\/div>
