The Level (lat. Norma) is an inconspicuous constellation of the southern hemisphere. The brightest star is abinary starand 4.0 mag bright. In the constellation you may find many foggy objects of theMilky Way.
After the invention of the telescope, the French astronomerNicolas de Lacaillenamed some constellations of the southern hemisphere that had not been recognized before. Unlike the 48 constellations of antiquity, which bear the names of mythological figures, he often used the name of technological novelties for the new constellations. Out of faint stars of the constellations Lupus, Scorpius and Ara, de Lacaille formed the Level and presented it under the name "Norma et Regula". In 1930, some of those stars were assigned to Scorpius again, so that there are no stars of Norma called α or β.
