Precision engineered instrument with ""retro"" styling appeal Provides a map of the night sky, labelling major stars and constellations (has both northern and southern hemisphere versions included plus field of views for different latitudes). Easy to use - Each section rotates separately from the others. Line up the month and date section (left section) with the time (middle section) by rotating the sections till you have the current date and time lined up with the white markings meeting. Hold the scope vertically with the poles aligned correctly (east facing east, west facing west).
