Bonjour
J'ai enfin fini mon image de la grande galaxie d'Andromède M31 que j'avais déjà traitée il y a 3 ans, mais sur laquelle j'ai plus que doublée les temps de poses.
Comme d'habitude, tous vos commentaires sont les bienvenus ..:-)

Hi
I finally finished my image of the large Andromeda galaxy M31 that I had already processed 3 years ago, but on which I more than doubled the exposure times.
As usual, all your comments are welcome .. :-)
