Cette nuit d'été déjà assez courte, fut très belle en visuel. Ce fut plus délicat pour la photo car nous étions partiellement gênés par la fumée de l'incendie de début de mois de Saint-Jean-d'Illac. Ceci explique le peu de poses cumulées pour cet objet qui en aurait demandé le double (au minimum). J'ai eu un mal fou à faire ressortir un peu de couleurs et je ne suis pas satisfaite de l'image finale.

Cependant, je la garde car les aigrettes sont marrantes, on peut y voir les amas globulaires M4 et NGC 6144, et ça me permettra de comparer avec la prochaine que je ferais de ce champ d'étoiles autour d'Antarès dans la constellation du Scorpion, sûrement l'année prochaine.

Photo prise le 11 juillet 2015 à Saucats (33) - Canon 350D défiltré avec objectif 55-200, focale à 55mm, ouvert à f/5,6, sur monture Orion Sirius EQ-G motorisé (sans autoguidage ni goto).

16 poses de 4 mn – 15 DOF – ISO 800 – IRIS et Toshop.

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.
