Description

M33 is the first galaxy for which I try a composition in Ha-LRGB. I had already taken a picture with my EOS700D towards the end of the year 2017 (AAPOD of March 31, 2018).
The treatment gave me a lot of trouble to keep a good balance between the details and the intensity of the colors.

Le traitement m'a donné pas mal de soucis pour garder un bon équilibre entre les détails et l'intensité des couleurs.
