M57, the Ring Nebula

M57, the Ring Nebula in Lyra.

This is a planetary nebula located about 2000 light years away. When low-mass stars like our Sun reach the end of their red giant stage they expel their outer layers creating a shell of ionized gases that are illuminated with a remnant white dwarf at the center.

EXIF

  • Lights: 15" ISO 800 x 22
  • Darks: 10
  • No flats. Something went wrong with the flat frames and they made the image look worse. Need to check why this is happening.

Gear

  • William Optics ZenithStar 81 doublet apo
  • William Optics Flat 6IIIa 0.8x reducer
  • HEQ 5 Pro
  • Canon 700d
