M3 ONLY STARS

M3 · conosciuto anche come NGC 5272. Questo ammasso si trova nella costellazione dei Cani da caccia ed è uno degli ammassi più visibili del cielo, insieme a M5 e M13. L'ammasso globulare M3 si trova a circa 33.900 anni luce dalla Terra e ha un'età stimata di 10 miliardi di anni.
L'ammasso globulare M3 si trova lontano da stelle ben riconoscibili. Può essere di aiuto sicuramente l'allineamento delle stelle beta e gamma della costellazione Chioma di Berenice, oppure la stella Arturo può essere utile per localizzarlo almeno approssimativamente. La sua declinazione è tale che può essere visto, in momenti diversi dell'anno, in entrambi gli emisferi. Il momento migliore per osservarlo in Italia è la primavera. La sua magnitudine apparente è pari a +6,3, il che lo rende appena osservabile a occhio nudo in condizioni visuali eccezionali. L'ammasso è già visibile con un binocolo come una debole macchiolina, ma con un telescopio di 20 cm rivela tutta la sua maestosità, pur essendo naturalmente apprezzabile anche con diametri più piccoli.

Ho elaborato l'ammasso separano la nebulosità centrale emessa dalle stelle per render maggiormente visibili le stelle blue del nucleo

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.
