Sur 3 nuits (17\/09-13\/10-14\/10\/21<\/em>), d’abord en plan large avec ma petite lunette de 275mm, puis avec mon Ritchey de 1550mm voici la n\u00e9buleuse IC 1396 <\/strong>dans la constellation de Ceph\u00e9e<\/strong>. Vaste objet circulaire mais difficile \u00e0 observer sans filtration (46 images de 60sec minimum en HAlpha principalement<\/em>). La seconde image n’est pas un zoom dans la premi\u00e8re, c’est une photo r\u00e9alis\u00e9e le lendemain, toujours filtr\u00e9e, de l’ensemble que l’on appelle “la trompe de l’\u00e9l\u00e9phant”. Perso je vois plus une femme myst\u00e9rieuse qui nous regarde…<\/span>

Lunette ED de 60mm,275mm de focale avec r\u00e9ducteur aplanisseur (plan large)<\/em>
