Le ciel clair de Rixensart de ce 14 octobre m’a incit\u00e9 \u00e0 pousser une nouvelle fois le \u00ab\u00a0Mewlon 180\u00a0\u00bb dans ses limites en r\u00e9\u00e9ditant une s\u00e9rie sur NGC 7662, ce petit objet n’apparaissant que sous forme ponctuelle dans mes autres instruments.
\nA f12, \u00e7a va un peu mieux, sauf pour le guidage, qui a beaucoup de boulot.
\nLe \u00ab\u00a0plus\u00a0\u00bb se trouvait en fin de prise de vues, l’essentiel du travail \u00e9tant alors de s\u00e9cher tout le bazar qui semblait avoir travers\u00e9 la cascade de Coo (par exemple).<\/p>\n

Technique: Mewlon 180 c, EOS 60 Da r\u00e9gl\u00e9 \u00e0 ISO 800, sans aucun filtre (l’instrument semble aimer la pollution lumineuse), 109 poses de 1′ 45 soit environ 3h.10 au total, darks, flats et offsets.
\nTraitement par Simon-Pierre Gorza sous Iris.
\nIl semble en conclusion que la formule \u00ab\u00a0Mewlon\u00a0\u00bb n’est pas, comme indiqu\u00e9 souvent, uniquement destin\u00e9 au \u00ab\u00a0plan\u00e9taire\u00a0\u00bb.
\nC’est vrai aussi que dans \u00ab\u00a0n\u00e9buleuses plan\u00e9taires\u00a0\u00bb, le terme n’est pas absent.<\/p>\n
