Mosaïque entre Céphée et Cassiopée SHO

Je ne vais pas refaire en détail la description de cette image que j’avais déjà réalisé en HOO. Voici donc la version SHO de ce grand champ composé de 3 panneaux dans la constellation de Céphée et Cassiopée. Ce champ mesure 4d 59’ 17’’ x 2d 58’ 58’’. On y trouve sh2-170 appelée aussi la petite rosette, abell85 ou CBT1, sh2-173 appelé la nébuleuse du masque de l’opéra ainsi que la nébuleuse planétaire Ou2 (découverte par Nicolas outters) et une nouvelle candidate MoMi4. J’ai effectué une astrométrie annotée pour vous montrer ces différents objets que j’ai complété. (Annexe sur astrobin) La recherche de nébuleuse planétaire a le vent en poupe en ce moment avec la paire Marcel et Xavier qui font des découvertes incroyables appuyées aussi bien par des astrophotographes amateurs que des télescopes professionnels. La paire Sankalp Mohan et Utkarsh Mishra commence également la quête de recherche de NP. (D’où le MoMi4)Avant d’être officiellement déclaré Nébuleuse planétaire, elle passe, entre autre, dans les mains de pascal Le dû qui effectue une spectroscopie. Cette spectroscopie permet de vérifier la correspondance des raies et de faire un 1er tri avant de l’envoyer pour confirmation à Andreas Ritter et Quentin Parker au LSR de l’université de Hong Kong.

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.
