This image has captured a northern corner of Cygnus. There is the alpha Cygni, Deneb, at just outside of left edge of the image, you can detect the glare of it in the image.
Two round reddish nebulae are paralleling in north south direction in the image, southern and northern nebulae are Sh2-112 and Sh2-115, respectively.
Both have sizes of 15 or 20 arc minutes, we can take their tiny figures easily by photographing the constellation of Cygnus with a wide photo lens.
Furthermore, you can recognize a smaller reddish nebula of Sh2-116 at 40 arc minutes northwest of Sh2-115.
Although the nebula has an ID of planetary nebula (PK 85+4.1), actually it's only region where hydrogen gas has gathered densely by chance.
