NGC7822

NGC 7822 In Hubble Palette
Stelle giovani e calde , pilastri cosmici di gas e polvere sembrano affollarsi in questa splendida nebulosa ad emissione . NGC 7822 si trova ai margini di una gigantesca nube molecolare , denominata Sharpless 171, verso la costellazione settentrionale di Cefeo che sfiora la sua vicina Cassiopea . All'interno della nebulosa, bordi luminosi e forme scure risaltano in questo colorato panorama celeste . L' immagine che vedete include dati acquisiti con filtri a banda stretta per circa 15 ore , che mappano le emissioni di ossigeno terzo, idrogeno e zolfo secondo nelle tonalità blu, verde e rosso .Ho utilizzato una tecnica fotografica studiata dalla nasa per riprendere gli oggetti del profondo cielo con il telescopio spaziale Hubble che permette di avere ottime immagini , anche sotto un cielo inquinato , che scientificamente vi indicheranno la composizione in cui sono fatte le nebulose.

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.
