SH2-132
Cropped section that got slightly different processing in December 2022 :
Cropped (& rotated) section from the Top Image in August 2022:
SH2-132 is a large emission nebula in the constellation of Cepheus. It is located on the southern edge of the constellation, a short distance from the border with the lizard, along the plane of the Milky Way. The most popular time for observation in the evening sky falls between the months of November and December for observers situated in the northern hemisphere. SH2-132 is located at a distance of almost 3200 parsecs (almost 10400 light years), and is thus within the Perseus arm, The stars responsible for its gas ionization are very hot and massive stars; in particular two Wolf-Rayet stars have been identified, HD 211564 and 211853 (the latter having also the abbreviation WR 153), as well as a star of spectral class O V 8.5 and a dozen stars of class b.
It can be glimpsed visually, but that takes a rich-field refractor and very dark skies.
