Crescent Nebula and Surroundings

Presenting the famous Crescent Nebula or NGC 6888. My main goal was to make little shy "Soap Bubble" visible.

I also managed to capture another interesting object:
The star to the right below the center of the image is P Cygni, representative of a class of variable, very rare blue supergiants. The stellar wind produces a so-called P Cygni profile in the spectrum. P Cyg is one of the most luminous stars in our galaxy. In the vicinity of P Cyg you can see hints of OIII filaments, which are possibly due to an earlier outburst of the star: https://cxielo.ch/project/p-cygni-nebula/.
In any case, a connection to the star seems to be obvious - otherwise how could a nebula shining in OIII exist there.

Hope you enjoy the picture. Any comment is appreciated.

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.
