Cúmulo globular Messier 3

Os comarto esta nueva captura mejorada utilizando minnuevo autoenfocador RB-Focuser, en la cual comparado con la anterior version, es muy notable la diferencia de punto de enfoque y nitidez.

Cúmulo globular catálogado por Charles Messier como Messier 3 ó NGC5272. Se encuentra a unos 33.900 años luz de la Tierra. M3 tiene una magnitud aparente de 6,2, Este cúmulo es uno de los más grandes y brillantes: según cálculos recientes se compone de alrededor de 500.000 estrellas, aunque su masa es próxima a las 800.000 masas solares, ubicado en la constelación de Canes Venatici, junto a M 3, un poco mas arriba a la derecha en la imagen también se observa una pequeña galaxia lejana, NGC 5263.

Capturado como siempre desde mi terraza en plena ciudad, bortle clase 8/9.

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.
