Komet C/2022 E3

Nachdem ich wochenlang warten mußte endlich geschafft.
Eine Wolkenpause am 29.01.2023 & 02.02.2023 konnte ich für ein paar LRGB Aufnahmen nützen.
Die Verarbeitung erfolgte mit PI .

Infos zum C/2022 E3:

C/2022 E3 (ZTF) ist ein Komet des Sonnensystems mit unspektakulären Schweif und einer langen Umlaufzeit.
Im Januar 2023 näherte sich der Komet der Sonne und erreichte am 1. Februar 2023 seinen nächsten Punkt zur Erde.
Während seiner Reise zog er in der Nähe des Polarsterns vorbei und war mit etwa 5. Größe mit freiem Auge sichtbar.Die ungewöhnliche grüne Farbe der Koma des Kometen wird vermutlich durch das Vorhandensein von zweiatomigem Kohlenstoff (C2) im Kometenkopf verursacht.
C2-Moleküle existieren normalerweise nur bei sehr hohen Temperaturen in der Gasphase und emittieren bei Anregung durch ultraviolette Strahlung hauptsächlich im Infrarotbereich.
Allerdings strahlt der Triplett-Zustand des C2-Moleküls bei 518 Nanometer (grünlich). Es entsteht durch Photolyse von organischen Materialien, die aus dem Kern des Kometen verdampfen.
Das grüne Leuchten ist nur im Kopf des Kometen zu sehen und nicht im Schweif, da es der Photodissoziation unterliegt und eine Lebensdauer von etwa zwei Tagen hat.Das Spektrum des Kometen zeigt zahlreiche Emissionslinien von NH2, C2 und [OI] im Spektralbereich zwischen 5000 und 7000 Å.

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.
