Jones-Emberson 1
Captured from a backyard observatory in Romano d’Ezzelino, Italy, under the light-polluted Bortle 7/8 skies, this image showcases Jones-Emberson 1 (PK 164+31.1), a faint planetary nebula located approximately 1,600 light-years away in the constellation Lynx. Nicknamed the "Headphone Nebula" due to its distinctive shape, this relic of a dying star’s outer layers appears as a delicate bubble of ionized gas, glowing faintly against the backdrop of space.
The nebula, around four light-years across, is a testament to the star's final stages of life. At its heart lies a fading white dwarf, the exposed core of the progenitor star that has shed its outer layers. The intricate structure and subtle colors in the nebula result from the interaction of ultraviolet radiation from the white dwarf with the surrounding gas, causing it to fluoresce in blues and greens, particularly in oxygen emission lines.
Imaging this elusive object from a bright suburban sky was a challenge, but careful planning and advanced post-processing brought its delicate features to life. Despite the light pollution, the faint circular shell and central star are clearly resolved, a testament to the dedication and skill of the astrophotographer.
Fun Fact: Jones-Emberson 1 was first cataloged in 1939 by R.C. Jones and R.A. Emberson. Unlike more famous planetary nebulae like the Ring or Dumbbell Nebula, it remains a lesser-known gem, often eluding amateur astronomers due to its low surface brightness.
