Il s’agit d’un extrait de l’amas de la vierge que j’ai choisi pour essayer (je pense avec succ\u00e8s) le r\u00e9ducteur de focale, qui aplanit aussi le champ.
\nLes principales galaxies dans le champ de 1.5\u00b0x1\u00b0 sont, en partant du coin sup\u00e9rieur gauche:
\nNGC 4458 et 4461; ensuite la belle NGC 4438 et 4435; puis la grosse elliptique M86 entour\u00e9e de NGC 4402 au dessus, NGC 4425, 4403, 4388 et 4387 en dessous; et enfin l’elliptique M84; passons sous silence les IC…<\/p>\n

\"\"<\/a><\/p>\n

ST-10 sur l’AP 130 @4.5; 12 poses de 5 minutes avec guidage.
\nSoustraction du dark, deblooming (et si, malgr\u00e9 le peu d’\u00e9toiles…), filtre DDP dans CCDOps; alignement, addition et histogramme dans CCDSoft; ajustement du fond du ciel dans IRIS.<\/p>\n
