Sh2-112 is bright emission nebula within a large Milky Way molecular cloud inside Cynus. I really like this particular image/target, as it juxtaposes the bright emissions lit up on the far side of young stars, with the dark nebula on the near side that casts shadows. Yet is isn't terribly often imaged.
I hazard to guess that it is younger than wither the Fly stellar nursery (NGC1931), or the Cocoon Nebula (IC 5146). However, it does seem to form an archtypical structure with many that I would guess are older (the Tadpoles, 1C410 ; Elephant Trunk, IC1396 ; Little Rosette, SH2-170; Clamshell Sh2-119 and Rosette, NGC2244). All are roughly doughnut shaped with heavy [OIII] and usually visible star cluster in the middle, a doughnut of Ha/[SII] around it, fading to week emissions from the background molecular cloud. In the molecular cloud, fragmentation and collapsing can be seen that will ultimately form additional stars.
SH2-122 is 5600 ly away, a little over twice as distant as the Elephant Trunk.
