    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 impressively 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.
