Bonjour à tous,

Je vous présente ma M31 dite la Galaxie d'Andromède pour ne plus la présenter. C'est photo m'a demandé beaucoup de temps de traitement, notamment à cause de la grosseur et de la quantité des photos de la 6200 ^^
C'est une composition RVB et HA, j'ai volontairement pas poussé le HA, je ne trouve pas ca naturel quand le HA prédomine le reste de la galaxie. Vous remarquerez aussi que je n'ai pas mis les IFN de HA, je trouve aussi que cela dénature la galaxie.

Pas moins de 650x15" pour la couche RVB et 120x120" pour la couche HA faite au DUAL (IDAS NBZ), j'ai bien sur séparé les canaux pour ne garder que la couche rouge.

Pour le traitement, je suis partie sur un smooth process comme je les appelle. Essayer de garder une cohérence entre les couleurs, la saturation et les étoiles. Tout à été fait sous PIX / PS.
Un process simple basé sur XNoise / Xstart et les composantes de base ACDNR / PixelMath.

N'hésitez pas l'ouvrir en grand, les détails y sont fins et bien définis ! Merci la 6200 ^^

Au plaisir les coupains !
Bon ciel.

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.
