Voici une vue \u00e9triqu\u00e9e du r\u00e9manent de supernovae Sharpless 240. La s\u00e9ance s’est arret\u00e9 brusquement \u00e0 cause d’un connecteur DC de ma cam\u00e9ra. La soci\u00e9t\u00e9 Moravian a re\u00e7u et r\u00e9par\u00e9 la cam\u00e9ra en 15 jours y compris l’envoi ! Merci Moravian, merci Pavel.<\/p>\n
