About This Item


Tato mince je zcela funkci, muzete ji pouzit pri nocni orientaci a zjistit tak svou zemepisnou polohu.
This is a functional nocturnal coin which you can actually use to tell time during the night and get your latitudinal deviation.
The nocturnal navigational tool stood the test of time. Its purpose is to tell time at night so you can gain a more accurate latitude and longitude reading. The first written evidence of a nocturnal was discovered in the year 1272. It was refined in the 1500s to tell more accurate time and was used well in to the late 1800s and partially used into the early 1900s. Two disadvantages of the Nocturnal is it can only be used at night, and only when the pole star Polaris and either of the dippers are visible. However, it also had a great advantage since it can be used at night when a sundial could not be used. The nocturnal can only be used in the northern hemisphere unless you know how to triangulate the southern axis point, but the deviation scales can only be used in the Northern Hemisphere. Using a nocturnal in conjunction with a quadrant will yield a more accurate latitude reading. The use of a planisphere is most helpful to find the correct stars to use.
