      DESCRIPTION
      PaStDr5 is probable new planetary nebula in the constellation Lyra, in the center of the large Lyra-HII region.
      Discovered by Marcel Drechsler, Xavier Strottner and Dana Patchick and photographed by Markus Blauensteiner.
      The nebula shows a very prominent blue OIII bubble, surrounded by H-alpha filaments and resembling a pearl.
      The potential central white dwarf has very good properties and is most likely the source of the ionization of the structure.
