Notes

Sh2-187 is a young and compact HII region in the constellation of Cassiopeia. Located about 1.5° north of the star δ Cassiopeiae (Ruchbah), which causes the diffraction pattern at the bottom.

The presence of star formation can be identified in the numerous infrared sources discovered in the nebula.
