Les nuages ayant enfin pris le parti de laisser du r\u00e9pit aux astronomes, l’occasion \u00e9tait r\u00eav\u00e9e de faire des images du Soleil \u00e0 l’aide du spectroh\u00e9liographe Sol’ex. Il est ici mont\u00e9 sur une lunette Evostar de 72mm, mont\u00e9 juste apr\u00e8s le renvoi coud\u00e9.
En tournant la molette bleu ciel, on fait tourner le r\u00e9seau dispersif, ce qui permet de choisir la longueur d’onde dans laquelle faire la prise de vue (sur la cam\u00e9ra que l’on voit en rouge sur la photo).

Toutes les images ont \u00e9t\u00e9 r\u00e9alis\u00e9es le 5 avril par Pascal Berteau.<\/p>\n<\/div>\n\n\n\n
