NGC 7380 - Wizard nebula - Ha-RGB (Rodolphe Goldsztejn)

NGC 7380 - Wizard nebula - Ha-RGB

Revision title: Softer processing

[EN]
This one gave me a hard time. The halos on the stars were very pronounced. The Ha-R merge was degrading the stars.
Finally, I merged the Ha into the R by removing the continuum, in starless mode, then put the new Red+Ha back into the RGB.
Then mounted the histograms by hand (Ha and RGB independently), combined channels, separated the stars and processed the object for contrast, noise, sharpness.
The stars were processed separately by reducing the gamma and increasing the vibrance slightly.
I then reintegrated the stars and finalized the image by reducing the halos.
Comments are welcome!

Celle-là m'a donné du fil à retordre. Les halos sur les étoiles étaient très prononcés. Le merge Ha-R dégradait les étoiles.
Finalement, j'ai fusionné le Ha dans le R en supprimant le continuum, en mode starless, puis ai réintégré le nouveau Rouge+Ha dans le RGB.
Puis ai monté les histogrammes à la main (Ha et RGB indépendamment), recombiné les canaux en mode LRGB, ai séparé les étoiles et ai traité l'objet pour le contraste, le bruit, la netteté.
Les étoiles ont été traitées séparément en rduisant le gamma et en augmentant légèrement la vibrance.
J'ai ensuite réintégré les étoiles, puis ai terminé en réduisant les halos sur l'image finale.
Les commentaires sont les bienvenus.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
