The shape of this isolated cloud, as well as the spatial distribution of young stars in GAL 110-13, may have caused either shock fronts from a supernova or ionization fronts from a massive star. GAL 110-13 is elongated and points roughly in the direction of the star 10 Lac. So this possibly indicates that either the star Lac OB1b or 10 Lac is responsible for forming the cloud.

The blue reflection nebula, vdB 158, is located in the center of the cloud in the image. The nearby bright star B9.5V, HD 222142, illuminates vdB 158.

As a small bonus, PK 110-12 1, a small planetary nebula, is located in the upper right of the image. Luboš Kohoutek discovered the PN in 1963 and distance estimates range from 13.8 to 17.1 thousand light-years.
