Petite pr\u00e9sentation en images sur une NJP Temma 2 : $\"\"$ <\/a>L’image obtenue donne un champ gigantesque de 11.46\u00b0 par 7.64\u00b0 ! Ici, l’image de M13 en 10 minutes de pose permet d’atteindre la magnitude de 14.5.<\/p>\n

$\"\"$ <\/a>La r\u00e9duction des 4 coins montre pourtant la limite de l’objectif en pleine ouverture, la correction n’\u00e9tant pas compl\u00e8te sur tout le champ !<\/p>\n
