Abell 6 (PK 136+04 1 and others) at the center of the image, is a planetary nebula located approximately 3,154 light-years away.

HFG1 (PK 136+05 1 and others) at the top left, is a planetary nebula located approximately 2,308 light-years away.

Both of these are located about four degrees from the heart nebula (IC 1805) in Cassiopeia.
