NGC 6820 is the red patch of nebulous gas in the upper right. NGC 6823 is the open cluster within the nebula.
Located in the constillation Vulpecula, the cluster is said to be about 2 million years old and about 6000 light years distant.

Just to the lower right of image center is another open cluster known as Roslund 2.

About half way between the image center and lower left corner there is a red blotch, cataloged as LBN-138 (Sh2-87).

Sh2-88 also known as LBN-139 is paritally included at the lower left edge.

Just to the left of the bright star in the lower left LBN-137 is just above LBN-138.

Since the image is in the Milky Way, the dust and dark lanes are visible throughout the image.
