Cher tous,<\/p>\n

Ci-joint une \u00ab\u00a0petite\u00a0\u00bb photo de la fameuse n\u00e9buleuse North America dans le Cygne, encore commun\u00e9ment appel\u00e9e NGC7000, photographi\u00e9e par mes soins \u00e0 l’aide de ma petite lunette BORG 76ED (encore elle!) ouverte \u00e0 f 6.7. Ce clich\u00e9 a n\u00e9anmoins n\u00e9cessit\u00e9 pas mal de patience puisqu’il constitue une mosa\u00efque de 12 photos prises avec la cam\u00e9ra Audine \u00e9quip\u00e9e d’une CCD KAF401-E et d’un filtre IR-cut Baader.<\/p>\n

Chaque clich\u00e9 est le r\u00e9sultat d’un compositage m\u00e9dian de 10 poses de 2 minutes en suivi libre (sans guidage) avec ma GP-DX. Le traitement reprend la soustraction du noir et la division par la plu (comprenant la soustraction de l’offset).<\/p>\n

La plus grosse difficult\u00e9 r\u00e9side dans l’assemblage de photos prises \u00e0 des jours diff\u00e9rents et donc dans des conditions de transparence et de turbulence diff\u00e9rentes. Mais je pense que le jeu en vaut la chandelle et encourage tous ceux qui souhaiteraient se lancer dans le champ moyen sur base du petit KAF401.<\/p>\n

Si vous d\u00e9sirez ce clich\u00e9 en haute r\u00e9solution ou pour de plus amples informations, n’h\u00e9sitez pas \u00e0 me contacter sur mon mail priv\u00e9 (adresse ci-dessus).<\/p>\n

Bien \u00e0 vous,<\/p>\n

Alain<\/p>\n
