Trois amas pour une nébuleuse

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

En ce dimanche de début mars, nous avions environ 1h30 entre le crépuscule astronomique et le lever de Lune. Le beau temps semblait vouloir perdurer… alors j'installais mon setup sur la terrasse pour renouer avec l'astrophotographie… je n'avais rien fait depuis le 25 janvier.

Avec une pollution lumineuse moyenne, il me fallait choisir un objet lumineux et, si possible, inédit à mon bestiaire. Je visais donc M47 que je voulais associer à M46. Au cadrage, je m'aperçu que l'APN n'était pas dans le bon sens si je voulais avoir les deux amas. Je le tournais donc l'appareil sur le PO. Mais, de cette manœuvre, il semblerait que l'alignement fut touché car j'ai des étoiles qui filent en haut à gauche et à droite de l'image… puis, bien avant le lever de Lune, ce sont les nuages qui ont fait un retour prématuré, me gâchant pas mal de poses.

Malgré cela, l'ensemble offre un bestiaire bien sympa avec en bas à gauche l'amas d'étoiles M46 avec la nébuleuse planétaire NGC 2438, en haut à droite l'amas d'étoiles M47, et entre les deux l'amas d'étoiles NGC 2425.

Faut que je retente ce champ avec mon Samyang ;)

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.
