Lors des Nuits astronomiques de Touraine, la météo nous avait gâtés et nous avons pu bénéficier d’un magnifique ciel nocturne. Il était encore tôt lors de cette première nuit alors que les Antennes venaient de se cacher derrière les arbres. Je décidais donc de pointer une nébuleuse assez classique et facile : l’Anneau de la Lyre. 57ème entrée du catalogue Messier, elle est également cataloguée NGC 6720.

Située dans la constellation de la Lyre, l’un des sommets du Triangle d’été, cette nébuleuse planétaire (issue de la mort d’une étoile de type solaire) est à une distance de 2.300 années-lumière. Elle a été découverte en 1779 par Antoine Darquier de Pellepoix. Le diamètre réel de l'anneau est de 2,4 années-lumière.

Je trouve cette image assez réussie, même si l’Anneau se perd un peu dans le champ d’étoiles. Sur la full, on peut voir, juste au-dessus de l’Anneau, IC 1296, une galaxie spirale barrée à deux bras. Il serait peut-être intéressant que je refasse quelques poses supplémentaires afin de révéler plus de détails sur cette galaxie. A suivre donc ...

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.
