Comme signal\u00e9 par Dominique, il faisait beau hier et il convenait d’en profiter.<\/p>\n

En lumi\u00e8re blanche<\/strong><\/p>\n

Lunette TS 155, Prisme de Herschell, Filtre Solar continuum + ND 0.9, ASI 1600<\/p>\n

Gain=0, Exposition=0,0840ms, stack de 30 images<\/p>\n

 <\/p>\n

En Calcium double stack :<\/strong><\/p>\n

ERF Bi-bande Antlia 150, Lunette 155 TS, Baader K-line, Alluxa Ca 0.1 nm, Antila 393 3 nm, 2\u00e8me Alluxa Ca 0.1 nm, Asi 1600<\/p>\n

Les filtres sont thermor\u00e9gul\u00e9s par un excellent syst\u00e8me de mon ami Alex.<\/p>\n

Malheureusement la r\u00e9gulation du 2\u00e8me filtre n’a pas fonctionn\u00e9, je crois que c’est parceque la chambre de ce filtre n’\u00e9tait pas isol\u00e9e comme la premiere par 2 autres filtres.<\/p>\n

Malgr\u00e9 la recommandation d’essayer au minimum F 16, je trouve le r\u00e9sultat satisfaisant \u00e0 F 8.2, c’est cependant un peu cram\u00e9<\/p>\n

Gain=0, Exposition =2,0540ms, stack de 20 images<\/p>\n

 <\/p>\n

En H-alpha<\/strong><\/p>\n

SM90, TV 101, Alluxa H-a 10 A, ASI 183<\/p>\n

Gain=0, Exposition=0,0450ms, stack de 50 images<\/p>\n

A titre de comparaison, avec mon BF 15 droit j’avais 0.43 ms d’expo, 10 x plus…<\/p>\n
