Description

Suite et fin des traitements sur Messier 17, cette fois-ci c'est une LhaRVB avec une luminance de 50/50 entre les images des filtres CLS et Halpha.
Peu de différences entre celle-ci et la HaRVB déjà postée sauf pour les étoiles plus présentes et la nébuleuse moins étendue ..
La LHa en noir et blanc va suivre .............
