the seagull nebula

Here is my first astrophotography of 2022. This is the seagull nebula cataloged IC 2177 about 3800 light-years away in the direction of the Linicorn constellation.
This is a huge cloud consisting mainly of hydrogen gas, and in other proportions of oxygen, sulfur and other even heavier elements ionized by hot new stars by their intense ultraviolet radiation.
Two large HII clouds make up the seagull nebula. The first is the SH 2- 296 which forms the body and wings of our celestial bird, this formation is a nursery of stars that shape the molecular clouds around by their powerful stellar winds. The second gas cloud is SH 2- 292, which forms the head of the seagull. This cloud is more compact and possibly derives its characteristics from the star HD 53367 (the eye of the seagull).
Other smaller neighboring molecular clouds are part of this cosmic scene including SH 2- 293 and SH 2- 295 which add a degree of wonder to this region of the sky.
The show is not yet over as two open clusters invite each other to the party, these are NGC 2343 and 2335.
Finally, let's note the gigantic shock wave compressing the cloud near the star catalogued HD 53974. The latter is a blue subgiant whose radial velocity of about 32 km/s is probably the cause of this wave.

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.
