The Cave Nebula (SH2-155) is a faint emission nebula in Cepheus, which also has a minor reflection component as well.  In this field of view can also be seen the faint Herbig Haro object HH-168 (formerly known as GGD 37), as well as the pretty reflection nebula vdB 155, which are labeled in the rollover.  More information about this region can be found on Rob Gendler's website here.
