Emission nebula in constellation Cygnus.
Sh2-114 is a weak emission nebula in the constellation cygnus and has a slightly torn shape. The area obviously consists of several arcuate filaments lying on top of each other.

The arcs have a semicircular shape with a depression facing south. It is suspected that this, together with the nearby Sh2-113 cloud, is a bubble shape that looks like a supernova remnant. To date, however, no supernova has been recorded or described in this region.
At the upper edge of the image is Kronberger (Kn) 26 - a bipolar emission nebula. A detailed analysis of the morphology and kinematics indicates the possible presence of two pairs of bipolar wings that would make Kn 26 a new member in the four-pole PN class.
The image was taken in 5 nights with over 24 hours exposure time from Ha, OIII and RGB images. Here the whole field:
