A deep wide‐field image in the light of the Hα and [N  ii ] 6548 &amp; 6584 Å emission lines, of the planetary nebula HFG1 which surrounds the pre‐cataclysmic binary system V664 Cas, has revealed a tail of emission at least 20 arcmin long, at a position angle of 316°. Evidence is presented which suggests that this is an  ≈10 5  yr  old trail of shocked material, left behind V664 Cas as it ejects matter whilst ploughing through its local interstellar media at anywhere between 29 and 59 km s −1  depending on its distance from the Sun.

A long trail behind the planetary nebula HFG1 (PK 136+05) and its pre‐cataclysmic binary central star V664 Cas
