Lors des pré-RAAGSO (du 5 au 7 septembre 2016), nous avons eu un ciel bien dégagé qui m’a permis d’imager. Le mercredi, après avoir capturé le Cœur, je voulais m’attaquer à la nébuleuse voisine, toujours en grand champ : la nébuleuse de l’Âme (IC 1848), une nébuleuse par émission, située à 6.500 années-lumière entre les constellations de Cassiopée et de Persée (tout près du Double Amas). Personnellement, je trouve que cette nébuleuse ressemble à un fœtus humain de 8 semaines. On peut y voir des amas d’étoiles dans le ventre et dans la tête. Au-dessus de la tête, on peut deviner une petite nébuleuse par émission cataloguée IC 1871. En bas de l’image, c’est une partie de la nébuleuse du Cœur (IC 1805).

Je n’ai pas l’habitude de cadrer aussi bien les objets que j’image… c’est un hasard si cette nébuleuse se trouve pile poil au milieu du cadre. Voici donc le résultat final que me plaît bien.

Photo prise le 7 septembre 2016 à Ambeyrac (12) – Canon 350D défiltré, objectif 55-200mm, focale à 55mm, ouvert à F/4.0, sur monture StarAventurer (sans autoguidage ni goto).

87 poses de 2 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.
