Notes

Sharpless (Sh-2) 113 and 114 are complex and unusual HII emission nebulas. The filamentary structures resembles a supernova remnant. However, no supernova remnant appears to be recorded for this location.
The wispy structures are likely the result of winds from hot, massive stars interacting with the magnetic fields in the interstellar medium. But very little is known about it.

There are also two planetary nebulas visible in the image:

Kronberger (Kn) 26 is a bipolar emission nebula. A detailed analysis of the morphology and kinematics suggests the possible presence of two pairs of bipolar lobes that would make Kn 26 a new member of the class of quadrupolar PN (www.aanda.org/articles/aa/pdf/2013/03/aa20592-12.pdf).

Kohoutek (K) 3-81 is a small planetary nebula, it can only be distinguished from the stars by its unusual color.
