The Constellation Sextans
by Dominic Ford
Sextans is a faint equatorial constellation which appears highest in the evening sky in the months around February.
It was introduced by the Polish astronomer Johannes Hevelius in 1687, covering a dark patch of sky immediately south of Leo, and represents a sextant, an instrument used to measure the positions of stars. Specifically, it represents Hevelius's own sextant, which was destroyed by a fire at his observatory in Danzig in 1679.
Its brightest star is of magnitude 4.5, and it contains no bright deep sky objects.
