SH2-132: The Lion Nebula

SH2-132 Lion Nebula was imaged by David Collings @ the Blue Ridge Observatory in Sparta, NC.

  • The telescope used was his PlaneWave 12.5” CDK with PW 0.66 Reducer sitting on an Astro-Physics 1100GTO CP4 mount.
  • Main camera is the ATIK 16200 Mono with EFW3 ATIK filter wheel loaded with narrowband Chroma filters.
  • This image is processed as an SHO (Ha, OIII, SII) with a total integration time of 10 hours.

The Lion Nebula Sh2-132, is an faint emission nebula located in the constellation of Cepheus. It can be found on the southern edge of the constellation, near the border with Lizard, along the plane of the Milky Way.  There are several embedded small dark nebulae and is estimated to be at a distance of roughly 10,000 light years from Earth. The core of Sh2-132 includes pillar-like structures, Bok globules, and the characteristic oxygen-rich stripe through the head of the Lion. The stars responsible for the ionization of its gas are very hot and massive; in particular, two Wolf-Rayet stars have been identified, known as HD 211564 and HD 211853.
