M13 à la ZWO2600MM

M13 est l'un des plus beaux amas globulaires de l'hémisphère nord. Situé à 25 000 al de la Terre, il abrite environ 500 000 étoiles dans un volume de quelques 145 al de diamètre. Situé dans la constellation d'Hercule, il peut être visible à l'œil nu sous un bon ciel loin de la pollution lumineuse.
Âgé de 12 à 14 milliards d'années, le grand amas d'Hercule est constitué d'étoiles très anciennes de couleur rouge, cependant on y découvre des étoiles chaudes, lumineuses de couleur bleue que l'on nomme "trainardes bleues", on suppose que ces étoiles se "régénèrent" par transfert de matière avec leurs voisines qui peuvent être très proches ou bien par fusion d'étoile, d'autres scientifiques proposent l'idée qu'elles se seraient formées à l'extérieur de l'amas pour ensuite être capturées par ce dernier.

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.
