description Overview

NGC 7139

NGC 7139 is a faint planetary nebula in the constellation Cepheus. It has a roughly circular appearance and a low surface brightness, making it more difficult to observe than compact, brighter planetary nebulae. The nebula lies approximately 3,300 light-years from the Sun and represents the expelled outer layers of a star that has reached a late stage of stellar evolution.

IC 289

IC 289 is a faint planetary nebula in the constellation Cassiopeia. It has a broadly circular shell and low surface brightness, so it is more difficult to observe and photograph than brighter planetary nebulae. The object is useful for observers studying the extended gas expelled by an aging star and for comparing the appearance of planetary nebulae at different stages of expansion.
