Astronomical Ring Astronomical Ring Ref: LH-H21

  • HEMISFERIUM
This sundial has the peculiarity of including a horizontal sundial as well as an analemmatic sundial. This combination of two sundials, based on different principles, on the same plate, offers an automatic guide to the direction of the meridian. For this reason a compass is not necessary. The hour you will obtain in the reading is in local time.  


Price:   £69.99 (Including: VAT at 17.5%)

Sextant Sextant Ref: LH-H25

  • HEMISFERIUM
This instrument is a reproduction of an Octant of the mid 17th century. By semi-accurately measuring the height of stars or the sun, the Octant allows navigators to determine geographic latitude.
In 1731 John Hadley (England) and Thomas Godfrey (Philadelphia, U.S.A.), demonstrated the Octant, independently. The arc of an Octant is 45º or 1/8 of a circle (hence its name) and is divided into 90 parts each ½ degree. The Sextant (1757) replaced the wood frame with metal and progressively took the Octant´s place. It is still used today.  


Price:   £145.00 (Including: VAT at 17.5%)

David Beringer's Quadrant David Beringer's Quadrant Ref: LH-H26

  • HEMISFERIUM
This model is a reproduction of a mobile cubic quadrant that dates back to 1736, and is thought to be the invention of David Beringer of Hapsburg (Germany).
It is made up of an articulated arm, which allows us to incline the cube in a North-South direction, and a plumb line on the eastern side that moves along a graduated scale and can be used to adapt the instrument to the latitude of the measurer.  


Price:   £50.00 (Including: VAT at 17.5%)
