IC 4634 is a planetary nebula with a striking point-symmetric morphology. Strings of line-emitting knots, particularly bright in [N II] emerge from its bright Hα core. These strings bend in opposite directions on either side of the nucleus. We have obatined sub-arcsecond monochromatic imagery that neatly reveals its main morphological components. Additionally, we also present a comprehensive kinematic mapping of the nebula, consisting of several long-slit echelle positions across the main components of the nebula.
