Pour réaliser ce mixage, j'ai réalisé une image H-Alpha et une RVB.
Exifs H-Alpha:
110x600s, sous un ciel SQM 20.35 chez moi à Avril, caméra refroidie à -10°C, 50DOF
Exifs RVB :
RVB 50x300s sous un ciel SQM 21.1 à Puzieux en nomade en compagnie de Yann SAINTY , caméra refroidie à -10°C, 20DOF
Matériel :

Lunette Takahashi FSQ 85 EDX
Caméra ZWO ASI2400MC
Monture équatoriale Sky-Watcher EQ6-R Pro pilotée via AsiAir PLUS
Filtre L-eXtreme de Optolong en 2" pour la couche H-Alpha

La couche Ha m'a servie de luminance pour augmenter les détails, faire ressortir les zones sombres tout autour et de peaufiner l'effet lumineux au centre, tout en ajoutant en plus une teinte rosée et violacée au RVB, palette de couleurs que j'adore particulièrement.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

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.
