Cometa 67P/Churyumov-Gerasimenko + Asteroide 126 Velleda

Soggetto: cometa 67P/Churyumov-Gerasimenko, finalmente questa elaborazione ha avuto un finale discreto.
Scoperta nel 11 Settembre 1969, per caso scambiata per un'altra cometa, ha un periodo orbitale relativamente breve di circa 6,45 anni dunque abbastanza ricorrente nei nostri cieli, ha un diametro di 4Km circa.
Nell'estate del 2014 questa cometa è stata avvicinata dalla sonda Rosetta.
Già visibile nel mese di Ottobre presso la costellazione dei Gemelli, a Novembre ha raggiunto il suo punto più vicino alla terra precisamente tre l'11 e il 12 Novembre, ma come spesso accade con questi eventi eccezionali le previsioni meteo non sono ma favorevoli, e anche questa volta ciò non si è smentito.
Le riprede degli scatti sono stati effettuati nella notte del 28 Ottobre per quasi 4h di riprese con scatti da 3min.
L'elaborazione non semplice ha ritardato un risultato finale degno di nota fino a oggi, l'immagine purtroppo non rappresenta il campo totale inquadrato ma è stato necessario croppare il campo inquadrato, per limitare l'influenza delle non perfette correzioni.
Dall'annotazione astrometrica fatta con PixInsght Tramite la generazione dei dati con il nuovo tool Ephemeridi, si possono vedere le coordinate del momento in cui sono state allineate le immagini e la magnitudine della cometa, cosa interessante anche è che nei frame è stato catturato anche l'asteroide 126 Velleda anch'essa con le coordinate e la magnitudine

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.
