La tempête solaire qui a commencé cette nuit en toujours en cours.
Si ça se maintient jusqu'à la nuit, on aura peut-être encore des aurores.
Prenez des photos longue pose en direction du Nord !

SH2-216, en SHO, en attendant qu'Orion se lève.
L'objectif étant de pouvoir configurer cette cible (fichiers de calibration, cadrage et test rapide d'un rendu).
Cible assez technique à première vue mais déjà un peu de signal visible :)
