Description

Cette nébuleuse avait déjà été reprocessée l'année dernière , mais je n'en étais pas complètement satisfait...Du coup pour une meilleure définition de la nébuleuse, j'ai ajouté 10 heures de Halpha pour la luminance. Le traitement est fait à partir d'images de 2017 & de octobre/novembre 2019

This nebula had already been reprocessed last year, but I was not completely satisfied ... So for a better definition of the nebula, I added 10 hours of Halpha for the luminance. The process is made from images of 2017 & October / November 2019
