NGC7000 + IC5070 le P\u00e9lican, photographi\u00e9s \u00e0 La Fosse sous un ciel correct mais pas du tout exceptionnel pour l’endroit.
\nMerci \u00e0 Alain de m’avoir appris la mise en station pr\u00e9cise de la monture Super Polaris qu’il m’a fournie \ud83d\ude09<\/p>\n

La 1\u00e8re image montre le champ total de 6,5 degr\u00e9s embrass\u00e9 par la courte focale alli\u00e9e \u00e0 un capteur demi-format.
\nLa seconde montre un crop en r\u00e9solution r\u00e9elle et trait\u00e9 un poil plus fort.
\n– T\u00e9l\u00e9objectif 200mm ouvert \u00e0 3.2, Canon 20Da, 800iso, filtre LPR, fils tendus devant l’objectif.
\n– 40minutes de pose accumul\u00e9es en 10x 4min, sans guidage \ud83d\ude00
\n100% Iris: darks et flats, pas d’offsets ni d’optimisation du noir sans doute inutiles pour les bo\u00eetiers \u00e9quip\u00e9s du processeur Digic II.
\nAddition, ddp, \u00ab\u00a0black\u00a0\u00bb sur le fond de ciel modifiant tr\u00e8s peu la balance des couleurs choisie pour le d\u00e9codage des raws (RVB = 1,1,1).
\nLa prochaine fois, j’essaierai la m\u00eame sans filtre.
\nOli S<\/p>\n
