Description:
HFG1 (Heckathorn-Fesen-Gull 1) and Abell 6 make for a interesting pair of planetary nebulae (PN). Abell 6 is in the lower right of the image and has the bubble look of most PNs. The nebula has a blue/green look from ionization of OIII. Abell 6 has a fairly strong Ha component as well. Discovered in 1982, HFG1 (PK 136+05) is in the centre of the image, and it has a more complex structure. The planetary nebula is formed from the binary star, V664. The binary system is comprised of a white dwarf, and a large red giant star. The two stars are very close and rotate about each other in just 14 hours.
