Bonjour,
\nVoici une photo (r\u00e9duite \u00e0 50 pc) de l’amas globulaire M3 faites ce samedi 16 mai depuis le col de la Faucille dans le Jura. Cette image a \u00e9t\u00e9 prise lors d’un test d’autoguidage (c’est ce qui explique le mauvais cadrage) de la G11 Gemini. 6×5 minutes en binning 1×1 pour chaque filtre en mode LRGB avec la ST10XME au foyer de la lunette Televue NP101IS. On peut voir la petite galaxie NGC5263 \u00e0 droite de l’amas.<\/p>\n

\"\"<\/a><\/p>\n

J’ai ensuite imag\u00e9 M57, cette fois en mode L(ha)gb. 6×5 minutes en binning 1×1 pour la luminance et 6×2 minutes en binning 2×2 pour les ha g b. Avec seulement 540mm de focale, la n\u00e9buleuse est \u00e9videmment tr\u00e8s petite sur l’image.<\/p>\n
