Planetary Nebula Kohoutek 1-20
History
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.» [436] 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.

Finder Chart
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 June to February, when it is highest at night.
