\nMalgr\u00e9 la Lune j’ai voulu faire un essai hier.
\nLes opportunit\u00e9s sont en effet rares.
\nCa fait de l’entrainement…
\nFinalement le r\u00e9sultat me para\u00eet satisfaisant,
\navec des n\u00e9buleuses obscures il n’en sans doute pas ainsi.<\/p>\n

100 x 2 min avis Asi 2600 MC
\nLunette 155 F8 avec r\u00e9ducteur 0.8 soit 992 mm focale.<\/p>\n
