Orion à l'arraché

Le mois de novembre ayant été pourri, décembre voulait à tout prix lui ressembler. Cependant, lors de la soirée du vendredi 12, l'animation satellite montrait un dégagement possible. Je montais donc le setup dans le jardin. J'avais choisi d'imager M1, la nébuleuse du Crabe, mais au vu des premières poses, j'ai renoncé. La pollution lumineuse était trop importante pour un objet si faible. J'ai donc attendu que la constellation d'Orion se dégage du haut sapin du voisin et j'ai visé M42, la nébuleuse d'Orion.

Il était déjà tard et j'ai abrégé les poses, d'autant que le froid était arrivé en même temps que l'éclaircie. J'ai jeté la moitié des poses car il y avait quand même pas mal de passages nuageux et certains poses étaient "trop rouges", sûrement dues au faisceau laser qu'on a vu balayer le ciel en début de soirée, quand les nuages étaient présents :roll:

J'ai eu un mal fou au traitement mais finalement, le résultat n'est pas si mal ;)

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.
