Cygnus Loop (HOO) - Sharpless 103

English:

The Cygnus Loop is a supernova remnant in the Cygnus constellation. It is a remnant of a massive stellar explosion 5,000 to 8,000 years ago. The nebula stretches three times the size of the full moon in the night sky and is around 1,500 light-years from Earth.

My first picture in HOO. I'm happy with the colors. Apparently I had a back focus problem, the stars in the corners didn't turn out completely round.
The picture was taken over 4 nights in September and October 2023 from my south-facing balcony in Berlin (Bortle 6-7).

Deutsch:

Der Cygnusbogen ist ein Supernovaüberrest im Sternenbild Schwarn.Er ist ein Überbleibsel einer gewaltigen Sternexplosion vor 5.000 bis 8.000 Jahren. Die Cygnus-Schleife erstreckt sich über die dreifache Größe des Vollmonds am Nachthimmel und ist rund 1.500 Lichtjahre von der Erde entfernt.

Mein erstens Bild in HOO. Bin zufrieden mit den Farben. Anscheinend hatte ich ein Backfocus-Problem, die Sterne in den Ecken sind nicht ganz rund geworden.
Das Bild ist über 4 Nächte im September und Oktober 2023 von meinem Süd-Balkon in Berlin enstanden (Bortle 6-7).

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.
