This relatively bright region in the constellation Cygnus is famous for its resemblance to the North American continent, including a prominent Gulf of Mexico area. The Wall section is the bright region of Hα emission that runs along the lower edge of the frame. This image is over 19 hours of data, primarily in Hα and OIII, with about an hour's worth of RGB data used for the stars.

The area made famous by the Hubble 'Pillars of Creation' image is also accessible to amateurs to image. This is a modified palette mixing the 3 typical narrowband filters into a modified SHO result.

Both the "Eagle" and the "Star Queen" refer to visual impressions of the dark silhouette near the center of the nebula,[3][4] an area made famous as the "Pillars of Creation" imaged by the Hubble Space Telescope. The nebula contains several active star-forming gas and dust regions, including the aforementioned Pillars of Creation.
One of the most beautiful areas of the night sky visible from the Northern Hemisphere, the Rho-Ophiuchi Nebula Complex shows off a myriad of colors in this natural light image captured through LRGB filters. There are also a number of globular clusters visible in the image, the most prominent example being M4, almost directly below the very bright star Antares, which is located in the bright golden area of the image.

At an estimated distance of 131 ± 3 parsecs,[2][4] this cloud is one of the closest star-forming regions to the Solar System.[5] Additional details can be found at this Wikipedia link: https://en.wikipedia.org/wiki/Rho_Ophiuchi_cloud_complex
