La comète ZTF mais pas forcément celle qu’on croit !

Le 2 février, alors que la plupart des astronomes avaient leurs yeux et leurs instruments braqués sur la comète C/2022 E3 ZTF, j’ai vu qu’une autre comète passait tout près de Cassiopée et de l’amas NGC 457, populairement appelé l’amas d’E.T. Cette comète, cataloguée C/2020 V2, a été découverte en novembre 2020 par le programme de relevé astronomique « ZTF » (Zwicky Transient Facility) qui utilise le télescope de l’observatoire Palomar.
Moins brillante que sa célèbre consœur C/2022 E3, cette comète se dirige vers le Soleil dont elle sera au plus près que début mai à environ 2,23 UA.

Photos prises dans la nuit du 2 au 3 février 2023 à Ayguemorte-les-Graves (33) – Canon 40D défiltré partiel + filtre clip EOS L-enhance, avec objectif Sigma 70-300, focale à 190 mm, ouvert à 5,6, sur monture StarAdventurer (sans goto ni autoguidage).
339 poses de 60 s pour le film (156 retenue pour l’image) – ISO 1600 – 25 DOF – Iris, VirtualDub et Toshop.

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.
