Revision title: Allez, encore une autre!

Profitant du confinement pour revoir d'anciennes captures...

Je me pose des questions sur la lunette (Meade 127 ED APO) que j'ai acquise il y a une bonne dizaine d'années.

La capture a été effectuée en juin 2019, avec un suivi... approximatif, et sans luminance.

Traitement avec AstroPixelProcessor et finalisation dans LightRoom.

Les halos bleus autour des étoiles me gènent... est-ce la qualité du cliel, de la lunette ou du filtre?

Vos commentaires seront les bienvenus.

Title: New capture with the CMOS camera

Description: Surprisingly less frames conducted to this outcome - between 50 minutes and 1 hours per channel.
Need to fix the blue halos on some stars, visible on Bode's galaxy - sky quality was not the best.

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.
