This object, first identified by Kazaryan and Parsamyan in 1971, is a unique small faint planetary nebula located 6000 light years away in the constellation of Cassiopeia. This object is located less than 1 degree from the famous Bubble Nebula (NGC 7635).

This image is a Ha-RGB image. I also took OIII subs but that signal is much fainter than Ha for this object, so I did not use the OIII subs for this image.

The unique shape of this PN is believed to be caused by bipolar ejections in changing directions from a binary star.  The 2 primary ejection axes are shown in the mouseover.  The length of this PN is about 11 arc-minutes, which corresponds to about 20 light years. The bright central oval around the progenitor star is only 4 arc-seconds in diameter.  

The best description of this object is the abstract of the excellent 2000 paper entitled “The Formation of a Multiple Planetary Nebula: Hubble Space Telescope / WFPC2 Observations of KjPn 8”:

“KjPn 8 is an extreme polypolar planetary nebula with a large-scale structure characterized by a giant biconical envelope. Spasmodic bipolar ejections in changing directions have occurred over thousands of years to create this peculiar nebula. Narrowband images of the core of KjPn 8 have now been obtained with the Wide Field Planetary Camera 2 on board the Hubble Space Telescope (HST) and are reported here. The central star is finally revealed in these observations, and its compact nebular core is resolved into a remarkably young elliptical ring, currently expanding at only 16 km s~1. This ring is the ionized inner region of larger molecular CO and counterparts, all sharing the same orientation. The highest H2 speed and youngest outflows are perpendicular to this central ring, which is identified as the latest event in the creation of this nebula. It is shown that the formation history of KjPn 8 has involved two distinct and consecutive planetary nebulae-like events, probably originating from a binary core evolution with components of very similar mass. These characteristics indicate that KjPn 8 may be a rare object in our Galaxy and the first ever detected of this class.”
