Following the discovery of a long trail behind the planetary nebula HFG1 (Boumis et al. 2009), we performed single- and multi-slits high-resolution echelle spectroscopy covering both the bow-shock and the long tail of this PN. Furthermore, we performed 2-D hydrodynamical simulations of the cometary structure of this PN. Both the kinematic and modeling results are presented here.
