NGC6992

La Nebulosa Velo Orientale è un grande resto di supernova visibile nella costellazione del Cigno.
È una nube in espansione creata dalla morte di una stella esplosa. Si ritiene che la luce di questa esplosione di supernova abbia raggiunto la Terra circa 5000 anni fa.
Per le riprese ho utilizzato un telescopio Schmidt Cassegrain C11, con riduttore di focale che lo pota da 2800 mm a 540 mm , ossia da F10 ad F1.9.
Per tale rapporto focale, ho utilizzato un filtro interferenziale a banda Stretta, al fine di isolare i gas ionizzati Ossigeno ed Idrogeno. Il rapporto focale veloce F1.9,consente una raccolta di luce tale da ridurre i tempi di esposizione . Nel contempo genera dei problemi per i quali è necessario installare la camera di acquisizione ad una precisa distanza di back focus.

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.
