AR3141 et 3140 en continuum et en proche UV

Recommended Posts

Salut !

 

Une image du jour des beaux groupes de taches AR 3141 et AR 3140 prise avec ma lunette TS Photoline de 125 mm munie d'un filtre ND5, une caméra Altaïr GPCAM2 290M équipée d'un filtre Altaïr contrast booster (continuum à 540 nm) et une barlow Televue Powermate de 2,5x.

Et une autre prise sans la barlow avec filtre Altaïr NUV centré sur le proche ultraviolet à 395 nm.
