M 77 - 8 novembre 2013 (Giuseppe Nicosia)

M 77 - 8 novembre 2013

M 77 è una galassia "attiva". Presenta un nucleo molto luminoso e delle spirali poco sviluppate. E' considerata il prototipo delle galassie di Seyfert. La più grande difficoltà da superare nella foto è riuscire a evidenziare un anello di stelle che circonda la spirale. Nella mia foto questo obiettivo è stato raggiunto in maniera davvero difficoltosa, perché si vede a stento. Probabilmente ci vuole più integrazione oppure occorre un cielo molto meno inquinato rispetto a quello cittadino da cui fotografo. Nella foto sono stato costretto ad eliminare intensi aloni (che ancora in realtà si vedono) dovuti all'inquinamento luminoso.

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.
