Open Clusters NGC7129 and NGC7142 in Cepheus
Reflection nebula IC5134 envelopes NGC7129 and reflects light from the hot blue young stars, a stellar nursery with red emission nebula regions excited by emissions from the giant young stars. The red cresents are Herbig-Haro objects, ionized hydrogen gas compressed by shock waves emitted by the stars.
Edge-on galaxy PGC97261 is just to the left of NGC7142.
Galaxy PGC168098 is on the upper left edge of NGC7142.
Galaxy PGC168082 is above NGC7142.
