On the backside, there is a nocturnal, like those used by ancient sailors to place the brightest circumpolar stars and aid their nightly observations.

This piece is fashioned of brass and comes complete with wooden stand, cotton plumb line with brass pearl and booklets explaining use and history. The wooden base is ideal for placement of a commemorative plaque in recognition of achievement or an event.
