Une mouette pleine de ressources !

Le 3 février, alors le beau temps persistait en Gironde, j’ai pointé une grande nébuleuse d’environ 2° dans le ciel de la Terre (soit 4 pleines lunes). D’environ 100 années-lumière de long, située à environ 3.800 années-lumière de la Terre, à cheval sur les constellations du Grand Chien et de la Licorne, cette nébuleuse à émission est cataloguée IC 2177. On l’appelle la nébuleuse de la Mouette à cause de sa forme qui fait penser au volatile marin.

Dans l’image annotée, on peut voir que cette nébuleuse pouponnière d’étoiles est composée de plusieurs petites nébuleuses à émission et amas d’étoiles ouverts. On peut aussi noter la présence de l’étoile variable pulsante SKF 1303.

Photos prises dans la nuit du 3 au 4 février 2023 à Ayguemorte-les-Graves (33) – Canon 40D défiltré partiel + filtre clip EOS L-enhance, avec objectif Sigma 70-300, focale à 190 mm, ouvert à 5,6, sur monture StarAdventurer (sans goto ni autoguidage).
312 poses de 60 s – ISO 1600 – 25 DOF – Iris, Astrosurface, Paint 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.
