Sh2-132 in Cepheus

SH2-132 is a faint HII region in the con­stel­la­tion of Ceph­eus, loc­ated in the Perseus spir­al arm of our home galaxy. It is believed that the optic­ally bright sec­tion of SH2-132 is excited by the massive O‑type star BD+55 2722 and the Wolf-Rayet star WR 153ab (=HD 211853).

There are a couple of OB stars loc­ated in the dir­ec­tion of SH2-132 which are mem­bers of the Cep OB1 asso­ci­ation. This implies that the true dis­tance is about 12’000 lightyears. Many back­ground inform­a­tions can be found in the paper from Vasquez et al. here.
