Troisi\u00e8me session avec ce montage \u00e0 \u00e9talon double stack, chacun r\u00e9gl\u00e9 individuellement en pression.<\/p>\n

Lors de la premi\u00e8re session, le train optique arri\u00e8re \u00e9tait mont\u00e9 sur le focuser au moyen d’un barillet 2″.
\nCe train optique p\u00e8se 1.9Kg, vous pouvez imaginer les probl\u00e8mes potentiels d\u2019orthogonalit\u00e9. Et la deuxi\u00e8me session a \u00e9t\u00e9 abandonn\u00e9e, ne sachant pas r\u00e9gler les filtres.<\/p>\n

Voici une troisi\u00e8me session avec un montage vissant du train optique arri\u00e8re, dans la mesure du possible.<\/p>\n

Le seeing n’a pas \u00e9t\u00e9 au RDV; le seeing a d\u2019ailleurs \u00e9t\u00e9 peu collaboratif cet \u00e9t\u00e9…<\/p>\n

J’ai donc fait des mosa\u00efques.<\/p>\n
