Planetary nebula KjPn 8 and Bubble Nebula

Planetary nebula KjPn 8 (PN G112.5-00.1, K3-89) and Bubble Nebula (NGC7635) in the constellation Cassiopeia.
KjPn 8 (PN G112.5-00.1, K3-89) is a bipolar planetary nebula which was discovered by M.A.Kazaryan and Eh.S.Parsamyan in 1971 and independently by Kohoutek in 1972. It is one of the strangest and possibly most unique planetary nebulae in the sky. In my image, we see it on the left side of the frame below the center. Planetary nebula consists of a compact red core (apparent size is about 3–4 arcsec in diameter) surounded by a huge bipolar lobe structure that measures 12x5 arcminutes. There is the possibility that the two separate structures are two separate planetary nebulae formed from both members of a binary star system moving onto the planetary nebula phase within a few thousand years of each other.
