Easily held in the palm of the hand, the Star Pocket provides quick and simple identification of stars by comparing them against a tiny illuminated built-in star map. An integrated compass provides alignment for two setting scales, one for the hour of day or night, the other for the month and approximate date. Pressing a button illuminates the star map to one eye while the other eye looks at the real thing in the heavens – same size, same shape and instantly recognisable. It will locate and identify 70 major constellations and 1,500 stars up to magnitude 5. Includes interchangeable star maps for Northern and Southern Hemispheres, plus four templates for adjusting latitude clipped underneath the compass. (Star Pocket is supplied ready for use in Europe, with a Northern star map preset for 40-50° latitude.) 145mm (6") long. Stores neatly in water-resistant drawstring bag. Two miniature batteries and full instructions in English included (other languages available). This product succeeds the larger Stellarscope (shown right) which has been hugely successful over the years. It performs all the same functions with even greater simplicity and with the extra advantage of a compass and illumination incorporated.
