Description

This object is a faint, rarely imaged planetary nebula located 1400 light years away in the constellation of Cygnus at a declination of +49 degrees. The nebula spans 3 arc-minutes in our apparent view. This corresponds to a diameter of just over 1 light year, which is typical for a PN.

This nebula was identified by Weinberger through a review of POSS prints. The nebula is the largest of 12 new ones documented in his 1977 paper, New Planetary Nebulae of Low Surface Brightness.

It is interesting to me that the outer edges of the nebula are blurred in some places. I assume that this is due to ISM interaction. Unlike most PN, it is not obvious to me which star in the image, if any, is the progenitor star. A significant amount of HII nebulosity appears in the image.
