This lovely wall-hanging instrument tracks both the tide and lunar cycles, ideal for predicting tide times and all important tidal heights. Phases of the moon are depicted as illuminated portions of the moon, as if looking up from earth into the night's sky.
Did you know that one half of the lunar surface is always illuminated by the sun (except during a lunar eclipse), and hence is bright, but the portion of the illuminated hemisphere that is visible to an observer on earth can vary from 100% (full moon) to 0% (new moon).
