Image Description and Details : Sh2-132 is one of the 312 bright emission nebulae catalogued by Stewart Sharpless. This large area of emission nebula in the constellation Cepheus glows from the characteristic red light of ionized hydrogen. Sh2-132 is about 1,200 light years away. Dark patches within it are due to soot blocking out the light. There are also some prominent dark nebulae blocking out the light of the stars behind them outside the main area of Sh2-132.

About two weeks ago, I processed a monochrome Hα image of this interesting object on the border of Cepheus and Lacerta. Last Monday the sky unexpectedly cleared. I decided to spend the night on acquiring OIII data to create an Hα-OIII-OIII false colour image, where Hα is assigned to the red channel, OIII to the blue channel and a mix of Hα and OIII to the green channel. Although it stayed clear all night, I only used the images captured before midnight. In the area in the Netherlands where I live, the sky severely brightens from midnight to dawn because horticulturalists are then allowed to ignite assimilation lights. Although the used OIII filter has a bandwidth of only 4nm, the light pollution caused by the glasshouse horticulture severely affects the quality (signal-to-noise ratio) of the images. I'll post a separate message to illustrate the difference in sky quality before and after midnight.

What's striking in (false) colour images of this object, is the conical beam that crosses in front of nebulas in the background. Here this beam has a cyan hue in front of yellow/orange nebulas.

Sharpless 132 is a very faint emission type nebula on the Cepheus/Lacerta border. It lies at a degree southeast of Epsilon Cep, and has a size of about 40 arc minutes.

Sh2-132 is located at about 10400 light years in the Perseus Arm of the Milky Way , in the region of Cepheus OB1, a large, bright OB association . The stars responsible for the ionization of its gases are very hot and massive; in particular, two Wolf-Rayet stars , known by the initials HD and HD 211 564 211 853 (the latter also having the initials WR 153), as well as a star of spectral class O8.5V and a dozen stars of class B.
