Jupiter with GRS at central meridian on November 18, 2023

Acquisition type: Lucky imaging

C’était une soirée comme beaucoup d’autres où se pose la question essentielle : les conditions sont-elles réunies pour l’astrophotographie ?
Le site météoblue prévoyait une vision très moyenne et un courant-jet supérieur à 20 m/s. Pas assez pour « sauter au plafond ».
Heureusement, le programme à la télévision était encore plus catastrophique, ce qui m’a décidé à affronter le froid sur mon balcon..
Je pense que j’ai fait le bon choix au vu du résultat, qui était plus que satisfaisant, à mes yeux.
L’écran de l’ordinateur présentait une image assez étonnante, avec une grande stabilité (pas de balancement de plusieurs pixels comme c’est souvent le cas à cette période de l’année) et un léger brouillard qui laissait néanmoins voir de fins détails.
J’ai donc le plaisir de vous présenter cette image de Jupiter avec la GRS au méridien central, qui permet de découvrir quelques détails en son centre.
La circulation atmosphérique dans la bande équatoriale de la planète est particulièrement intense.
Au sud de la GRS, on peut noter comme un cyclone en formation accompagné d’autres plus petits.
L’aspect de Jupiter dans l’image correspond à ce que je recherche, à la fois naturel tout en gardant la perception des détails.
Les couleurs sont celles données par les trois filtres (voir versions monochromes).
Seule une légère saturation a été nécessaire.
Bonne visibilité.
Filtre IR 610.
15 IRGB de 20 :53 UT à 22 :00 UT.

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.
