    StDr1 (PNG 185.1+-0.9) is a new spectrum confirmed planetary nebula (PN) in the constellation of Taurus.
    The PN was discovered in October 2019 by myself and my friend Xavier Strottner and photographed by our friend Rochus Hess.
    The potential central star of StDr 1 is located at coordinates 05:53:48.86 +24:02:41.45.
    If this star is used as a calculation basis, then StDr 1 is located at a distance of 9203 light years from Earth.
    For a PN at this distance, it is unusually bright.
    In addition, this photo was the first to detect an annular H-alpha structure around StDr 1.
