NGC 6888 - Emissionsnebel im Sternbild Schwan HOO / Sterne LRGB

Der NGC 6888, auch bekannt als der Crescent Nebula (Halbmondnebel), ist ein auffälliger Emissionsnebel im Sternbild Cygnus (Schwan).

Der Crescent Nebula hat seinen Namen aufgrund seiner Form, die an einen Halbmond erinnert.Er besteht aus einem sichelförmigen Schalenbereich aus leuchtendem Gas, der von einer heißen, massiven, jungen Zentralsternwolke umgeben ist.

NGC 6888 liegt etwa 5.000 Lichtjahre von der Erde entfernt.

Die Struktur des Nebels entstand durch die Wechselwirkung zwischen dem starken Sternwind des Zentralsterns, einem massereichen Wolf-Rayet-Stern, und den umgebenden Gaswolken.

Die energiereiche Strahlung des Sterns regt das umgebende Gas zum Leuchten an.

Die Ausarbeitung erfolgte in Pixinsight.
Sterne und Hintergrund wurden getrennt bearbeitet.
Die Entscheidung welche Version hochgeladen wird viel extrem schwer, da alle Varianten Für und Wieder haben ;)
Ich habe mich mal für diese entschieden...

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.
