Achird et la nébuleuse

Link to TIFF/FITS: https://flic.kr/p/EaF25w

Cette nuit-là, alors qu'un de mes 350D immortalisé le ciel "Au-dessus du Saut de la Mounine", le second APN fut mis au foyer de mon 150 pour une cible plutôt classique dans la constellation de Cassiopée : la nébuleuse par émission Pacman (NGC 281). Pour rendre le champ original, je décidais d'y inclure l'étoile Achird (η Cas – Eta Cassiopée) dans le coin supérieur gauche, ce qui délocalise la nébuleuse vers le coin inférieur droit.

Je suis satisfaite du rendu de cette image… on voit beaucoup de choses dans la nébuleuse, y compris des globules de Bok et des colonnes de gaz qui créeront probablement de nouvelles étoiles dans un avenir proche. De plus, Pacman est entouré de brillantes étoiles rouges, blanches et bleues qui font pétiller l'image. Bref, je suis contente du résultat !

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.
