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.

Hello, my name is Martin Rusterholz. I’m a Swiss amateur astrophotographer living near Zurich, the biggest town in Switzerland. My interest in astronomy started when I was 16. At that time, I built my first Newtonian telescope and mount. I studied physics at the Swiss Federal Institute of Technology (ETH) which was the only study including at least some aspects of astronomy and astrophysics.
“Looking at the nights sky is an experience touching everybody deeply inside, something common to all human beings independent to the language spoken by the individuals”.
Deep-sky astrophotography is my passion.
