   PK 164+30.1 is a planetary nebula in the constellation Lynx. The nebula has a low surface brightness with two brighter lobes. The outer red shell of expanding gasses expelled from the mag 16.8 blue star in the center are mainly hydrogen and the inner blue/green gasses are mainly oxygen. The inner gasses are thin enough to allow galaxies and stars behind it to be easily seen.
   PK 164+30.1 was first discovered by astronomers Jones and Emberson in 1939 (hence the name of Jones-Emberson 1) and later cataloged by Czechoslovakian astronomers Perek and Kohoutek in 1967. The unusual number is based on the galactic coordinate system relative to our galaxy instead of its relative position to Earth.
