NGC6559 - Star forming region in Sagittarius - "France nebula"?

Revision title: HOO

Image recorded across 3 nights in July 2022. It is sort of magic that an image comes out while pointing low on the horizon, just above the trees, in direction of city center’s light pollution, and - cherry on the cake - moon light. Narrow-band filters are a gift!

I found no nickname for this nebula, how about "France Nebula"? The shape of the nebula reminds me a bit the France Hexagon, with some additional peninsulae in the north coast...

*
NGC 6559 is a star-forming region located at a distance of about 5000 light-years from Earth, in the constellation of Sagittarius.

Visible are red-yellow glowing emission nebulae of hydrogen, blue reflection nebulae of dust, dark absorption nebulae of dust, and the stars that formed from them. The first massive stars formed from the dense gas will emit energetic light and winds that erode, fragment, and sculpt their birthplace. And then they explode. The resulting morass can be as beautiful as it is complex. After tens of millions of years, the dust boils away, the gas gets swept away, and all that is left is a naked open cluster of stars.

The nebula was discovered 196 years ago, on the 1st of July 1826 by John Herschel with his 48-cm telescope.

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.
