Depuis Li\u00e8ge-ville sous un ciel de mv_lim 3.8 sans Lune lors des 2 soir\u00e9es d’acquisition.
\nLunette SKW ED80\/600 avec r\u00e9ducteur WO 0.8x sur GPDX SkySensor autoguid\u00e9e.<\/p>\n

Essai de combinaison LRVB dans Iris avec le traitement DDP de la luminance dans AstroArt.
\n2,5 heures de pose avec le 350Dmod \u00e0 400iso + filtre UHC, addition Sigma dans Iris.
\n2 heures avec la CCD Sxv-H9 de 1.4Mpx + filtre Ha Astronomik 12nm, moyenne dans AA.
\nLes photosites de l’APN et ceux de la CCD ont une taille quasi identique facilitant le mixage (6.4\u00b5\/6.45\u00b5)
\nLes couleurs de cet objet semblent plus nuanc\u00e9es ainsi en HaRVB que d\u00e9livr\u00e9es par le seul APN.
\nImage en taille r\u00e9elle correspondant au capteur de la CCD<\/p>\n
