Description

Jones-Emberson 1, also known as PK164+31.1, is a beautiful planetary nebula in the constellation Lynx. Some people also call it the headphone nebula for obvious reasons. It resulted from the death of a sun-like star that expanded to a red giant and expelled its outer layers before collapsing to a white dwarf. The picture shows, both, the shells of gas expelled from the giant and a central blue dot, which is the remaining white-dwarf star.

The version A is a two-color narrowband composite from about 14 hours of Ha and OIII data. Version B is a LRGB composite of a total of 16 hours of data, where I use the narrowband data to enhance the luminance channel. Everything taken with the Astro-Physics RH-305 at the Deep Sky West Observatory.
