All sky watchers need a planisphere to quickly show the location of stars and constellations for any date and time. Note: Planispheres are designed for specific latitudes so be sure to select one for your latitude.

The Night Sky Planisphere

A very popular 8-inch diameter, two-sided planisphere (plastic) designed to depict the night sky with less distortion than regular planispheres. Available for several latitudes, and in a smaller 5-inch edition.
