Latitude Ranges:

Planispheres are produced for specific latitudes because the portion of the sky you will be able to see depends on where you are on the Earth. The farther north you are, the more of the northern hemisphere stars you will be able to see but the horizon will block more of the southern hemisphere. We produce our charts in more different latitude versions than any other major chart.
