1521814351Code 5838 Antique sextantSextant of brass signed Husun Trade Mark and made by Kelvin & Hughes Limited at the end of the thirties, company active for about 250 years and specialized in the creation of nautical instruments; instrument complete with optics and placed in an elegant original square box of oak wood with brass closing hooks and brass handle. Brass frame with engraved silver goniometric scale recessed into the arch, with scale from 0 to + 130, micrometric screw-type vernier with built-in illumination and reading nonius, ebonite handle containing night-lighting batteries, four glasses colored for the fixed mirror and three for the mobile mirror, index mirror and horizon. A label inside the box indicates 1961 as the date of the last check. Measures box 26x27.5 cm h 14.5.
In order to measure a height of a star (for example, the Sun), you have to set the instrument in a vertical plane and, looking through the sight device, to mark out the line of the horizon visible through the non-silvered half of the fixed mirror. Moving the alidade that is together with this mirror, make sure that the light rays coming from the star, and then reflected by the mobile mirror and by the silver half of the fixed mirror, be directed from the fixed mirror to the observer: if you look through the sight device, you see the image of the star, obtained for double reflection, coinciding with the line of the horizon. The height of the star is expressed by the angle whose value is read on the graduated scale. The filter is used when the star is the Sun.
