Acquisition type: Lucky imaging

Bonjour
Deuxième image de Jupiter de la session du 16 décembre dernier . Le ciel à 18H47 TU était un peu meilleur que pour la première image, ce qui se voit sur la qualité de la Planète..Sur cette image on peut voir 2 satellites (Europe & Ganymède) et l'ombre de Europe planait encore sur Jupiter (Io se trouvait en transit derrière la planète à ce moment là) .....
Le logiciel Winjupos toujours aussi performant a encore fait des merveilles, que ce soit à l'assemblage des images, qu'à la reconstruction de la position des satellites ....
Images issues de 12 vidéos (4R,4G,4B) de 90s chaque.

Toutes les images proviennent de vidéos monochromes :
vidéos avec filtres R,V,B:
Acquisition : 90s
Nombre d'images : ~7500 images
Temps d'exposition : 10ms

3% des meilleures images retenues ..

L'image B est annotée .

Comme d'habitude ,n'hésitez pas à m'envoyer vos remarques et commentaires !! ...
A bientôt pour de nouvelles aventures

Hi
Second image of Jupiter from the session on December 16. The sky at 6:47 p.m. UT was a little better than for the first image, which is visible in the quality of the Planet..In this image we can see 2 satellites (Europe & Ganymede) and the shadow of Europa still hovered over Jupiter (Io was in transit behind the planet at the time) .....
The Winjupos software, still as efficient as ever, has once again worked wonders, whether in assembling images or reconstructing the position of the satellites....
Images from 12 videos (4R,4G,4B) of 90s each.

All images are from monochrome videos:
videos with R,G,B filters:
Acquired: 90s
Number of images: ~7500 images
Exposure time: 10ms
gain: 320 (on average)
3% of the best images retained..

Image B is annotated.

As usual, don't hesitate to send me your comments !! ...
See you soon for new adventures
Georges

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.
