I tried reprocessing some data I captured from last February of this year (2020). I wasn't overly thrilled with my original results. While I am much happier with the results, I think perhaps this upcoming winter I may capture some more to add on to it. I'd still like a bit more definition in some of the structure on the outer edge and so forth. Maybe even add some RGB data for the stars in the future.
Jones-Emberson 1 (PK 164+31.1), also known as the Headphone Nebula, is a 14th magnitude planetary nebula in the constellation Lynx at a distance of 1600 light years. It is a larger planetary with low surface brightness. The 16.8-magnitude central star is a very blue white dwarf.
Discovered in 1939 by R. Jones and R. Emberson, its "PK" designation comes from the names of Czechoslovakian astronomers Luboš Perek and Luboš Kohoutek, who in 1967 created an extensive catalog of all of the planetary nebulae known in the Milky Way as of 1964. The numbers indicate the position of the object on the sky. ("PK 164+31.1" basically represents the planetary nebula that when using the galactic coordinate system has a galactic longitude of 164 degrees, a galactic latitude of +31 degrees, and is the first such object in the Perek-Kohoutek catalog to occupy that particular one square degree area of sky).
