Denier post sur l’imagerie solaire en ao\u00fbt.
\nIci, un filtre CaK est mont\u00e9 derri\u00e8re le T300.
\nLes temps d’exposition sont assez longs.<\/p>\n

D’image en image, la r\u00e9solution augmente, et \u00e9tonnement, la qualit\u00e9 aussi.
\nLa premi\u00e8re est prise \u00e0 8h13, la deuxi\u00e8me \u00e0 8h30, la troisi\u00e8me \u00e0 8h48 et la derni\u00e8re \u00e0 08h52.
\nInterpr\u00e9tation: plus le soleil monte, plus fine sera la couche d’atmosph\u00e8re, plus facile il sera d’imager.
\nEnsuite, la turbulence atmosph\u00e9rique prend le dessus (vers 8h50), et les images se ramollissent.<\/p>\n

Voici une tentative de capturer des protub\u00e9rances en CaK.
\nLe flux captur\u00e9 est tr\u00e8s faible et les temps d’exposition longs.
\nToutes sortes de r\u00e9flexions parasitent l\u00a0\u00bbimagerie. Les images qui suivent sous pass\u00e9es sous photoshop \ud83d\ude41<\/p>\n
