The Ring Nebula

This image of the Ring Nebula or Messier 57 was obtained using the Wide Field Camera on the Isaac Newton Telescope. It is a three-colour composite made from data collected using
filters to isolate the light emitted by hydrogen alpha (H-alpha), doubly ionised oxygen (OIII) and ionised sulfur (SII) atoms.
