La région du cygne est très riche pour les astrophotographes. On peut shooter n’importe où et avoir un gros signal. C’est le cas de cette région située juste à coté de Sadr, l’étoile centrale de la constellation du même nom. On peut y voir Simeis 57 appelé aussi propeller nebula et d’autres nébulosités. Des nébuleuses sombres apportent aussi pas mal de contraste sur cette image.

The Swan region is very rich for astrophotographers. You can shoot anywhere and get a big signal. This is the case of this region located just next to Sadr, the central star of the constellation of the same name. You can see Simeis 57 also called propeller nebula and other nebulosities. Dark nebulae also bring a lot of contrast to this image.

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.
