Bon, celui-l\u00e0, on ne le pr\u00e9sente plus! Le grand amas d’Hercule se trouve dans la constellation \u00e9ponyme. Il contient environ 100.000 \u00e9toiles et se trouve \u00e0 un peu plus de 25.000 ann\u00e9es-lumi\u00e8re de la Terre. Il est vu ici photographi\u00e9 depuis La Fosse le 08\/08\/2024 avec un APN Canon 700D d\u00e9filtr\u00e9 plac\u00e9 au foyer r\u00e9duit du C11 (F = 1777 mm) en 85 minutes par poses de 40 secondes \u00e0 800 ISO. Pr\u00e9traitement SIRIL puis traitement PIXINSIGHT et finitions avec PSP X Pro. La petite galaxie visible au bord sup\u00e9rieur de l’image est IC4617. Elle est beaucoup plus loin que M13 puisque sa distance \u00e0 la Terre est estim\u00e9e \u00e0 553 millions d’ann\u00e9es-lumi\u00e8re. Son diam\u00e8tre r\u00e9el est de 115.000 ann\u00e9es-lumi\u00e8re, ce qui en fait une galaxie semblable \u00e0 la Voie Lact\u00e9e.<\/p>\n

L’image est r\u00e9duite \u00e0 50% de la taille d’acquisition pour le forum.
