Sextans is a constellation created by Johannes Hevelius in the late 17th century. With it, the Danzig astronomer commemorated his own measuring instrument, a large sextant he used to determine star positions and which was lost when his observatory burned down. There is therefore no ancient myth. The constellation is very faint, with no star reaching fourth magnitude, and it lies near the celestial equator between Leo and Hydra. Of interest for telescopes are the Spindle Galaxy, NGC 3115, and the Sextans Dwarf Galaxy, a faint satellite of our Milky Way. From Central Europe Sextans stands in the south on spring evenings, just south of bright Regulus. You will need a dark sky to make out its stars.

Distances from the Hipparcos catalogue. For very distant stars they are uncertain – the year the light set off is therefore only a rough guide.
