Description:
PK 164+31.1, also known as Jones-Emberson 1, is a planetary nebula in the constellation Lynx. Its intricate structure and relatively faint luminosity make it a challenging target for astrophotographers. However, with patience and dedication, this “hidden gem” can be transformed into a stunning window into the deep sky. The nebula appears as a faint, diffuse spherical shell with an irregular structure. Its most striking features include internal rings and filaments, likely formed due to instabilities in the mass-loss process of the progenitor star. Hα and OIII filters reveal distinct details: OIII highlights the hotter, ionized regions, while Hα traces the denser gas.
