Le duo M81 et M82 est cette fois photographi\u00e9 avec la cam\u00e9ra ZWO 1600. Les d\u00e9tails sont bien visibles, et le rep\u00e9rage des autres galaxies pr\u00e9sentes \u00e0 l’aide de Pixinsight montre qu’il y a, comme souvent dans les champs de galaxies, beaucoup d’autres objets de ce type sur l’image. J’aime beaucoup la galaxie (nomm\u00e9e PGC28757) que l’on per\u00e7oit en dessous de M81…   <\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Voici une nouvelle version du couple M81 et M82 dans la Grande Ourse. Les d\u00e9tails dans les deux galaxies sont bien mieux visibles que sur mes images pr\u00e9c\u00e9dentes et l’image me semble proche du maximum que je puisse obtenir avec mon mat\u00e9riel, en terme de r\u00e9solution.<\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Un nouvel essai de photographie sur le c\u00e9l\u00e8bre couple de galaxies M81 et M82 dans la Grande Ourse. Les bras spiraux de M81 apparaissent un peu mieux que sur ma photo pr\u00e9c\u00e9dente, sans doute gr\u00e2ce aux poses unitaires plus longues accessibles par l’autoguidage.<\/span><\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Cette image faisait partie de celles que je r\u00eavais de faire, ce c\u00e9l\u00e9brissime couple de galaxies, appartenant \u00e0 la constellation de la Grande Ourse, m’ayant toujours fascin\u00e9. A gauche se trouve M82, encore appel\u00e9e la galaxie du cigare \u00e9tant donn\u00e9 sa forme, qui est l’une des rares galaxies \u00e0 pr\u00e9senter un aspect si contrast\u00e9 en observation visuelle. A droite on retrouve M81, dont le centre tr\u00e8s brillant \u00e9clipse quelque peu les longs bras spiraux de cette belle galaxie.<\/p>

Ce couple \u00e9tait id\u00e9al pour tester mon correcteur de champ. Gr\u00e2ce \u00e0 cet accessoire je peux ainsi photographier une zone du ciel couvrant presque enti\u00e8rement le capteur de l’APN, sans voir appara\u00eetre les d\u00e9formations d’\u00e9toiles caus\u00e9es par le F\/D 4 du t\u00e9l\u00e9scope. Voil\u00e0 qui ouvre d’int\u00e9ressantes perspectives.<\/p>
