Title: L-RGB, Ha not used finally

Description: Fully processed in PixInsight, final touches in LightRoom for contrast enhancements mainly.
Comments are welcome, as always.
Note the tiny galaxies at 7-8 hours from the main galaxy core: they started appearing only close to the end of the processing steps!

Title: Different processing approach

Description: L'image a été construite selon cette approche :

1. PixInsight pour le pré-traitement
2. APP pour l'assemblage LHaRGB, la balance des blancs, le retrait de gradient, sauvegarde en linéaire (TIFF)
3. retour dans PI:

* En linéaire:
** starnet V2 pour séparer les étoiles des objets
** réduction des étoiles avec MT
** accentuation de la saturation des objets (CS)
** réassemblage étoiles + objets (pixelmath)
** suppression du vert SCNR
** EZDenoise (TGV Denoise)

* Passage en non-linéaire:
** alternance de HT, Curves, et de CS

* Finalisation :
** LHE sur les objets

4. retouches finales dans LightRoom

Et voilà!

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.
