M 42 HaRGB

La Nebulosa di Orione (nota anche come Messier 42 o M 42, NGC 1976) è una delle nebulose diffuse più brillanti del cielo notturno. Chiaramente riconoscibile ad occhio nudo come un oggetto di natura non stellare, è posta a sud del famoso asterismo della Cintura di Orione, al centro della cosiddetta Spada di Orione, nell'omonima costellazione. Posta ad una distanza di circa 1270 al dalla Terra,si estende per circa 24 anni luce[5] ed è la regione di formazione stellare più vicina al Sistema solare. La cosa che mi meraviglia è che con poco piu di un ora di banda larga(1 he 20' con filtro L-pro) e 3 ore di halfa ( filtro baader da 7nm ) grasso da Guidonia Montecelio ( vicino Roma) sono riuscito a tirare fuori un bel segnale pulito e ben bilanciato.

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.
