\nEn l’occurrence, un miroir de 320 mm et un 255 mm.
\nLe traitement est bibande, r\u00e9fl\u00e9chissant le rouge autour de Ha et dans une moindre mesure, le bleu autour des bandes Calcim K et H.<\/p>\n

La filtration subangstr\u00f6m Ha est en simple stack.<\/p>\n

D’abord le 320mm, sa premi\u00e8re lumi\u00e8re.<\/p>\n

Divers essais de configuration de miroirs secondaires sont aussi pass\u00e9s au peigne.
\nAvec peu de diff\u00e9rence d’\u00e9chauffement du secondaire suivant les configurations.
\nLe seeing reste le facteur d\u00e9terminant.<\/p>\n

 <\/p>\n

Ensuite, un miroir de 255 pour utilisation nomade a \u00e9t\u00e9 trait\u00e9 en m\u00eame temps que le 320.
\nVoici sa premi\u00e8re lumi\u00e8re.
\nA nouveau, le seeing est un facteur primordial en imagerie solaire.<\/p>\n
