Properties

The constellation Microscopium, however, is a modest monument for the instrument of the same name. It is formed by several stars just slightly brighter than fifth magnitude and lies between Sagittarius and Piscis Austrinus. The area is 210 square degrees and the center culminates around midnight on August 4th. [9, 15]

History

Microscopium is another constellation from the series of technical and scientific devices that was introduced by Lacaille in the southern sky in the middle of the 17th century and was intended to fill the gaps between the major constellations. Here he immortalized the microscope, which became a revolutionary tool for naturalists and doctors in the 18th century. [7, 21]
