An uncommon bonus is that this image includes three members of the Sharpless Catalog of 313 HII regions. These are emission nebulae in the northern hemisphere. They are Sh2-192; Sh2-193; and Sh2-194. Sh2-192 is the very faint nebula in the middle of the image. Sh2-193 is the larger, still faint, nebula just below Sh2-192. Sh2-194 is the larger bright ball of gas to the right of both of the others.
Sh2-192 is an emission nebula located in the constellation Cassiopeia. Sh2-192 is part of a small group of nebulae. This group includes Sh2-193 and Sh2-194. They are located near the larger and well-known Heart and Soul Nebulae (IC 1805 and IC 1848).
