Ic 443- La nébuleuse de la méduse dans la constellation des gémeaux.
La nébuleuse de la méduse est difficile à mètre en valeur seule. Vu la taille angulaire très importante, l’askarFRA400 avec son réducteur qui ramène la focale à 280mm combiné à la zwo asi 294MMpro permet de l’avoir entièrement!
La couche OIII s’est fait désirer mais j’ai pu la faire un soir ou la lune étaient plus clémente (11%)
Le traitement est un régal car les possibilités de mixage sont multiples.
Pour le SHO, après mixage avec pixelmath, j’ai utilisé la méthode d’Eric Coles. Le principe est basé sur le travail sélectif de la colorimétrie en fonction des différentes zones de luminosité. Je trouve que cette méthode est très intéressante pour avoir une version qui change de l’ordinaire. Je suis passé par la starless pour le traitement grâce à starnett++ toujours aussi efficace!
Passez de bonnes fêtes les amis!!!😉

If this user has been harassing you, and you shadow-ban them, all their activities on your content will be invisible to everyone except themselves.
They will not know that they have been shadow-banned, and the goal is that eventually they will get bored while having caused no harm, since nobody saw what they posted.
You will remove your shadow-ban on this user, and their comments, messages, etc, will appear again on your content.

The Free account is not a way to keep your most recent or best 10 images on AstroBin, but a trial period for you to decide whether or not a paid subscription is worth it.

The image will be permanently deleted and cannot be recovered. All its revisions will be deleted too. Are you sure?
You will delete all other revisions (if any), and the originally uploaded image, leaving the current revision as the final and only version of this image.
