NGC6888 "Crescent" Nebula

NGC6888 conosciuta anche come Nebulosa Crescente, è una nebulosa diffusa nella costellazione del Cigno. Fu chiamata "Crescente" per il fatto che la parte più luminosa e visibile della nebulosa si trova ad occidente ed assomiglia quindi alla fase lunare con la gobba "a ponente" luna crescente. La nebulosa è il resto dell'esplosione di una supernova ed ha un'estensione di circa 16 anni luce. Immagine ripresa con Rifrattore Apocromatico Takahashi TOA130 e camera Ccd Sbig STL11000 su Losmandy G11. Elaborazione bicolour Ha+OIII effettuata dal "maestro" Francesco di Biase, integrazione RGB e elaborazione finale da parte del sottoscritto. Elaborazione HOIIIRGB. Filtri: Astrodon Ha 6nm, Astrodon OIII 6nm, Astrodon RGB. Ha 15x1200sec; OIII 9x1800sec, RGB 4x900sec. Località di ripresa Agriturismo Torre Doganiera e Casole d'Elsa - Siena - Italia

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.
