Trois comètes en deux jours !

Les 12 et 13 novembre 2020 durant le second confinement, j’ai sorti à nouveau mes setups dans le jardin d’Ayguemorte-les-Graves. Trois comètes étaient de passage et, pour 2 d’entre elles, je ne les avais jamais imagé. Donc, malgré la pollution lumineuse du lieu, je m’attelais à leur recherche.

Les images sont un peu pourrites mais les conditions étaient vraiment minables. Le gradient a été très difficile à traiter et reste imparfait, ainsi que l’équilibre des couleurs. Mais bon… comment résister à l’appel des comètes ?

La première, prise au 12 novembre, est 156P/Russel-LINEAR. C’est une comète périodique qui tourne autour du Soleil en environ 6,5 ans. Elle a été co-découverte par KS Russel en 1986 et par un observatoire automatique (LINEAR) en 2000.

Bien qu’elle fût faible en luminosité, j’ai tenté le grand champ car ce soir-là, elle au plus près de la planète Neptune, rapprochement apparent depuis le sol terrestre.

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.
