Planetary Nebula Kohoutek 1-20
The planetary nebula K 1-20 was discovered in 1962 by the Czech astronomer Luboš Kohoutek on the photo plates of the «Palomar Observatory Sky Survey» (POSS). He wrote: «On the red print there is a weak elliptical ring measuring 36" x 28" and 37 "x 31" on the blue print of the same shape. Central star 20.1 mag.»  The nebula was included in the «Catalog of Galactic Planetary Nebulae» (CGPN) compiled by Luboš Perek and Luboš Kohoutek in 1967 and was given the designation PK 110-12.1. 
The distance is given as 4207 parsecs. A value for an apparent brightness could not be found.

The Planetary Nebula Kohoutek 1-20 is located in the constellation Andromeda. A striking hexagon with the weak reflection nebula GN 23.35.4 serves as a locator. From there you shimmy along the stars about half a degree to the southeast. See 1° DSS inlet. The best time to observe is July to February, when it is highest at night.
