Bonjour,
\nDes conditions tr\u00e8s moyennes pour capturer cette galaxie avec le t\u00e9lescope de Pierre Ponsard install\u00e9 \u00e0 La Fosse. Outre qu’en cette p\u00e9riode de solstice d’\u00e9t\u00e9 le cr\u00e9puscule astronomique n’est pas atteint en Belgique, ce qui signifie que le ciel n’est pas absolument noir, il a fallu composer avec des passages de cirrus les deux nuits. Une brillante supernova, SN 2017eaw est apparue \u00e0 la mi mai et elle est toujours bien visible.
\nConditions d’amusement:
\nAstrographe ASA 12 Pouces de 305 mm de diam\u00e8tre, focale de 1104mm (F\/D = 3,62) avec correcteur de champ.
\nAPN Canon 350d refiltr\u00e9 Baader au foyer.
\n80 poses de 3 minutes \u00e0 400 ISO pendant les nuits du 19 et 20 juin 2017 (2 heures par nuit).
\nTemp. minimale le 19 : 21 \u00b0c
\nTemp. minimale le 20 : 18,5 \u00b0c
