Re: (IAAC) Obj: M37 (NGC 2099) - Inst: 8" F/6 Dobsonian
M1 is not a planetary nebula despite it being in the PK. That is one of
the many errors
propagated by the PK and hence in some popular US books. It is, as
mentioned by dave Mitsky classified as a supernova remnant or a bright
nebula. It definetly should not be classified as a PN. Wrong excitation
mechanism ,wrong expansion velocity, wrong method of formation.
