C 447 in Monoceros
IC 447 è una nebulosa a riflessione, che brilla di blu grazie alla luce delle stelle che si riflettono sul suo gas e sulla sua polvere. Conosciuta anche come nebulosa di Dreyer (in onore di chi l'ha catalogata) si pensa che faccia parte della stessa nube di gas e polvere che racchiude le nebulose Cono e Pelliccia di Volpe . IC 447 e' in buona compagnia , in alto c'e' la IC 446 mentre alla sua sinistra ci sono le piccole NGC 2247 e 2245 , altre e affascinanti nebulose a riflessione nidi di giovani e caldissime stelle.
Ho ripreso questo splendido campo cosmico Sabato 3 Febbraio in compagnia degli amici del GAS (Gruppo Astrofili del Salento) presso il Palazzo S. Spirito in localita' Stigliano (MT) , l'acquisizione e' stata effettuata con filtri a banda larga , L per la luminanza e in bin2 i canali colore RGB rispettivamente , infine segnale a banda stretta HA (idrogeno) dal mio osservatorio di casa Lunedi 5 . per una composizione in LRGB + HA .

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.
