Robur Carolinum as a constellation never gained popularity, probably because it used the star Eta Carinae and the Eta Carinae Nebula, and was soon dropped from use after only fifty years. Nicolas Louis de Lacaille also complained bitterly that it took some of the finest stars from Argo Navis. Its brightest star was Beta Carinae (β Car) or Miaplacidus, which was known as α Roburis or α Roburis Carolii.
