Jones-Emberson 1 (PK 164+31.1) 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 very blue white dwarf.

Discovered in 1939 by R. Jones and R. Emberson, it's "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).

This image consists of 24 RGB images all taken at -30°C at bin 2x2 for 15 minutes each. The luminance images are 15 minutes each binned 1x1 and at -30°. A total of 20 luminance images and 24 RGB images used for a total of 11 hours. All data was acquired using MaxImDl/CCD version 5.24 using ACP7.  Pix Insight version 1.8 was used for processing Dithered guiding was on.
