La Bulle sous une demi-Lune

Après un vendredi soir et un samedi soir au ciel couvert, le dimanche soir promettait quelques belles éclaircies. En cette fin novembre, le crépuscule astronomique arrive assez tôt et on peut se permettre de poser sans pour autant raccourcir sa nuit de sommeil. Au vu de l'animation satellite de ce 30 novembre, j'ai décidé de monter mon setup sur la terrasse de la maison de mon compagnon près de La Brède.

La Lune en premier quartier était bien présente au sud… il me fallait choisir une cible si possible éloignée de l'astre sélène et assez brillant car, malgré une situation géographique plutôt campagnarde, la pollution lumineuse du village est assez importante… C'est la nébuleuse de la Bulle associée à l'amas M52 dans la constellation de Cassiopée qui a eu ma préférence.

A défaut d'avoir la photo du siècle, j'ai pu assouvir mon manque en astrophoto… je n'avais rien imagé depuis le 25 octobre !

Photo prise le 30 novembre 2014 à Ayguemorte-les-Graves (33) - Canon 350D défiltré avec correcteur de coma Baader, au foyer d'un Newton 150 sur monture Orion Sirius EQ-G motorisé sans autoguidage ni goto.

94 poses d'1 mn – 15 dark – 15 flat – 15 offset – ISO 800 – IRIS & 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.
