Français : La galaxie du Triangle
également appelée M33, est une galaxie spirale appartenant au Groupe local et située dans la constellation du Triangle. Sans doute satellite de la galaxie d'Andromède. Situé à 3 millions d'années-lumière, c'est l'objet le plus lointain visible à l'oeil nu, encore faut-il disposer d'un site excellent et d'une très bonne vue pour déceler une très faible tache blanche... Cette galaxie est vue sous un angle de 54° par rapport à la ligne de visée depuis la Terre (une galaxie vue par la tranche le serait sous un angle de 90°), de sorte que sa structure peut être observée sans être trop gêné par les gaz et poussières du milieu interstellaire technique de prise de vue: Skywatcher Esprit 120ED AZ-EQ6 et Téléconvertiseur Nikon X2 1673mm de focale à F14 Nikon Z7 non défiltré 3h de pose en 36 x300sec à Hamois en Belgique le 07/10/2023 Logiciels utilisés, Siril, darktable et GIMP. |
