Session de traitement d’anciennes images de cet \u00e9t\u00e9.
\nVoici la n\u00e9buleuse de l’Halt\u00e8re, du Diabolo ou encore du Trognon de pomme \ud83d\ude09
\nElle s’appelle aussi Dumbbell ou encore M27 (27\u00e8me objet du catalogue \u00e9tabli par l’astronome fran\u00e7ais Messier).
\nElle est visible dans le ciel d’\u00e9t\u00e9 dans la constellation du Petit Renard; celle-ci est peu visible mais elle est en plein dans le \u00ab\u00a0Triangle d’\u00e9t\u00e9\u00a0\u00bb constitu\u00e9 de 3 \u00e9toiles bien connues – D\u00e9neb dans le Cygne, V\u00e9ga dans la Lyre et Alta\u00efr dans l’Aigle.
\nD\u00e9j\u00e0 visible avec une simple paire de jumelles, la n\u00e9buleuse d\u00e9voile ses atours au t\u00e9lescope qui permet aussi d’apercevoir l’\u00e9toile centrale (une naine blanche) qui a expuls\u00e9 son enveloppe gazeuse il y a environ 50.000 ans.
\nCette n\u00e9buleuse qu’on appelle \u00ab\u00a0plan\u00e9taire\u00a0\u00bb – mais vous l’aurez compris, qui n’a rien \u00e0 voir avec une plan\u00e8te – nous montre comment finira notre Soleil \u00e0 la fin de sa vie dans plus de 4 milliards d’ann\u00e9es.<\/p>\n

50 photos de 150 secondes ont \u00e9t\u00e9 prises avec un t\u00e9lescope de 280mm de diam\u00e8tre et une focale de 2800mm (F\/D:10).<\/p>\n
