+ Test divers : Modification Quark, Double stack r\u00e9glage \u00e9lectronique en pression, test BF<\/p>\n

J’utilise les newtons solaires sur le site de l’observatoire de St V\u00e9ran, ~3000m.
\nAvec les traitements bibandes et la charge thermique r\u00e9duite sur le train optique, je me suis essay\u00e9 d’imager pr\u00e8s de chez moi.<\/p>\n

D’abord \u00e0 partir de chez moi.
\nJ’habite en p\u00e9riph\u00e9rie de ville, o\u00f9 les propri\u00e9t\u00e9s sont accol\u00e9es les unes aux autres, avec des probl\u00e8mes inh\u00e9rents de turbulence.
\nCa a \u00e9t\u00e9 une surprise de pouvoir imager de chez moi avec un 250. Il est vrai que j’ai vis\u00e9 entre deux b\u00e2timents.

Ensuite pr\u00e8s de lacs, nous en avons 3 dans la r\u00e9gion.
\nIci, des essais divers ont \u00e9t\u00e9 faits.<\/p>\n

1\u00b0 Test d’un quark, dont le meilleur r\u00e9glage est obtenu avec le potentiom\u00e8tre call\u00e9 c\u00f4t\u00e9 froid.
\n\"\"<\/a><\/p>\n

2\u00b0 L’\u00e9lectronique du Quark a \u00e9t\u00e9 l\u00e9g\u00e8rement modifi\u00e9e, afin de ramener le potentiom\u00e8tre de r\u00e9glage dans une plage proche du centre bande Ha (Sous f25).
\n\"\"<\/a><\/p>\n

 <\/p>\n

 <\/p>\n

3\u00b0 Des essais en double stack: Quark + \u00e9talon lunt r\u00e9gl\u00e9 \u00e9lectroniquement en pression.
\nAvec 9 PSI (620 mBar):<\/p>\n

Avec 10 PSI (690 mBar):<\/p>\n

4\u00b0 Test de divers Blocking filters, dont l’Alluxa 10A ici \u00e0 l’oeuvre
