The Seven Sisters (The Pleiades), or Messier M45, located in Taurus. Seven or even more stars can be seen with the naked eye. The surrounding bright nebulosity can be glimpsed in rural skies with a telescope or good binoculars, particularly around Merope. Deep astroimages can show more nebulosity all around the field, mostly reflection blue nebulosity, due to interstellar dust reflecting and dispersing the light emitted by the most brilliant stars of the Pleiades. The nebulosity is due to a chance collision of the Pleiades star cluster with a cloud of interstellar dust. The dust particles have been aligned by the magnetic field between the stars showing a streaky structure of the nebulosity among the bright stars .
