HFG1 (also known as PK 136+05.1) is a faint planetary nebula in the constellation Cassiopeia. The rare morphological structure of HFG1 was formed by the mag 14.5 star V664 Cas which is actually a binary star system in which the two stars orbit each other every 14 hours. As HFG1 plows through the interstellar medium of the Milky Way a blueish OIII forward bow shock is formed and a faint red trail of Ha gas is left behind in its wake.
