Pour conjurer le temps gris, un peu de couleur par le Canon num\u00e9rique au travers d’un filtre de rejet de pollution lumineuse Idas LPS pr\u00eat\u00e9 par Pierre H. pour des essais au T400 f\/6 (Nandrin).
\n7 x 3 min de pose \u00e0 800 iso guid\u00e9es \u00e0 l’oculaire, balance des blancs sous Iris, fonction ‘black’ pour un ciel d’encre, le filtre Idas donnant une dominante vert \u00e9meraude \u00e9trange d\u00e9j\u00e0 \u00e9voqu\u00e9e par jlD.
\nCaptures r\u00e9alis\u00e9es sous un ciel brumeux (Voie Lact\u00e9e \u00e0 peine discernable dans le Cygne). Un test de 3 min sans filtre montrait un \u00e9cran tout orange de la diffusion de l’\u00e9clairage public.
