Albireo (TeBilePas)

Albireo

Albireo, magnifique étoile double dans le Cygne, encore une cible classique à visiter car même en visuel on peut distinguer les deux couleurs : bleu pour l'une et organgé pour l'autre...

C'est ma seconde photo "publiable", issue de la même nuit que la première (M13).

Les problèmes de MES et de guidage que j'ai eus n'ont pas vraiment d'impact, ici. J'ai voulu essayer rapidement juste avant de replier, la nuit étant déjà longue.

J'ai malheureusement fait des poses d'une seule durée et je pense que l'idéal c'est de passer par plusieurs durées différentes pour avoir une belle dynamique et un beau rendu (HDR). Vu le résultat que j'ai déjà ici, ma prochaine nuit vera très certainement une petite visite supplémentaire, elle m'a titillé, la belle paire ! ;-)

Pour la prise : 10x20 sec en L, 5x20 pour chaque RGB et enfin 50 offsets et 15 darks. A mon avis, pour la prochaine fois, je devrai faire des shoots de l'ordre de 10 sec. J'essaierai sans doute 10 - 15 - 20 pour chaque couche...

Ici, j'ai aligné et empilé le LRGB puis produit 3 images avec des stretching différents que j'ai combinées comme calques avec des opacités différentes pour donner ce 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.
