Lynds Bright Nebula 683

LBN 683, located high in Ursa Major just a little to the west of M81/M82, is a condensation of the dust that thinly permeates the entire area. Known as High Galactic Cirrus (HGC) or Integrated Flux Nebula (IFN), this dust is faintly illuminated by the light of all the stars in our galaxy. Bluish areas are where the dust is more strongly illuminated by nearby stars.
