Description

Image réalisée avec le superbe setup la team HAO à l'observatoire d'Oukaimeden au Maroc (2650m d'altitude). Un grand merci à de Aziz Kaeouach (@kaeouach aziz) qui m'a très aimablement permis d'utiliser l'instrument pendant une nuit !

Malgré la présence de la pleine Lune, 3h de pose ont été réalisées en Ha (50x 180s sans autoguidage) et ont été mixées avec mon image de cet objet avec une TSA102 en LRGB/HO, afin de récupérer la couleur.

Image realized with the superb setup of the team HAO at the observatory of Oukaimeden in Morocco (2650m of altitude). Many thanks to Aziz Kaeouach (@kaeouach aziz) who very kindly allowed me to use this instrument during one night!

Despite the presence of the full moon, 3 hours of exposure have been made in Ha (80 x 180s unguided) and have been mixed with my image of this object with a TSA102 in LRGB/HO, to recover the color.
