Catching a grown-up starfish planetary nebula - I. morpho-kinematical study of PC 22

We present the first part of an investigation on the planetary nebula (PN) PC 22 that focuseson the use of deep imaging and high-resolution echelle spectroscopy to perform a detailedmorpho-kinematical analysis. PC 22 is revealed to be a multipolar PN emitting predominantlyin [O III] and displaying m...
