Revision title: Autre essai de réduction d'étoiles, méthode Astroswell

Last version: the Moravian C3-2600, CMOS, was used to capture a whole new series over 3 nights.
Processing has also improved, compared to the previous outcomes.

Title: Nouvelles captures de juin 2022

Description: Caméra C3-2600, monture bien équilibrée, mise en oeuvre de la dernière version du process WBPP de PixInsight.
La couche L n'apporte finalement que peu de détails par rapport à la couche Ha - j'ai mixé les deux, ce qui a eu un effet bénéfique sur les étoiles.

I

Title: Star reduction - hope not too visible...

Description: New set of captures beginning of June 2022, over 3 nights - approx 100 subs, 20x600 sec per channel.
I mixed Lum and Ha for the luminance, but retrospectively, Ha could just have been enough for the luminance + RGB mix.
Made with the recentrly acquired Moravian C3-2600 CMOS camera (IMX 571).
Interesting to compare the outcomes with those I made in earlier versions of this image (CDD, and less agility with the post processing tools.)

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.
