NGC7023, FRA LE NEBULOSE OSCURE DEL CEFEO

CON LA STAGIONE GALATTICA ORAMAI ALLE NOSTRE SPALLE FACCIO IL PRIMO RIASSAGGIO DEL DEEP SKY SU SOGGETTI NEBULARI .
HO RIPRESO UN LAVORO INIZIATO L' ANNO SCORSO ED HO INTEGRATO A FAVORE DI UN MAGGIOR DETTAGLIO NEBULARE. CON LA TECNICA HDR DI PIXINSIGHT SONO PARZIALMENTE RIUSCITO A METTER IN EVIDENZA IL NUCLEO DELLA NGC7023, MA AD F2 CI SONO I LIMITI ( IN ME! ) E SI VEDE .. AD OGNI MODO SONO PER ORA SODDISFATTO.
NGC 7023 (talvolta nota come Nebulosa Iride o con la sigla C 4) è una nebulosa diffusa visibile nella costellazione boreale di Cefeo. Fu scoperta da William Herschel nel 1794. NGC 7023 è una nebulosa a riflessione, ossia riflette la luce di alcune stelle vicine; probabilmente la stella principale responsabile della sua illuminazione è proprio la stellina di settima grandezza, catalogata come HD 200775, la quale si troverebbe avvolta dalla nebulosa, assieme ad altre stelle meno brillanti nate dalle sue polveri e che vanno a formare l'ammasso aperto. La nebulosa dista da noi probabilmente circa 1400 anni luce e misura circa 6 al. ( fonte: wikipedia)

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.
