We present the star formation activity around emission nebula Sh2-112. At a distance of $\sim2.1$~kpc, this \ion{H}{2} complex, itself 3~pc in radius, is illuminated by massive (O8\,V) BD$+$45\,3216. The associated molecular cloud extends angular scales $2\fdg0\times0\fdg83$, corresponding to linear sizes 73~pc 30~pc, along Galactic longitude. high-resolution ($30\arcsec$) extinction map reveal...
