Information from the author
The prominent central bubble, hence the name of the nebula, is caused by massive solar winds of young stars in the center of the bubble.
This is a crop of a wider field, which you can see on the subsequent image. The field also includes the faint background nebula Sh2-161 and the highly turbulent Northern Lagoon Nebula (Sh2-158). In the top left of the wider field image you can see M52, the open star cluster also known as Salt-and-Pepper cluster.
I recorded this image over the course of multiple nights in September 2021 from my backyard observatory. Its an SHO / Hubble palette composite.
