La nebulosa Civetta (nota anche come Nebulosa Gufo o con le sigle M 97 o NGC 3587) è una nebulosa planetaria visibile nella costellazione dell'Orsa Maggiore.

M97 è una delle nebulose planetarie più complesse. Il suo aspetto è stato interpretato come una sfera senza poli, con gli occhi del gufo in corrispondenza delle zone povere di materia ai poli. La sua età è stimata in 6.000 anni.

Questa è stata dura....poi mettiamo anche il fatto che l'ho ripresa da Guidonia Montecelio, con cielo bortle 6 e SQM 19.26, cielo pietoso.

Altra cosa che mi ha dato ulteriore problema la presenza della luna al 96% (Luna calante).

La cosa che mi ha aiutato è stato l'utilizzo del filtro bibanda L-exstreme ( filtro da 7nm).

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.
