Planisphere Star & Constellation finderPlanisphere Star has an innovative design with a Two Sided Disk. Side 1 has a detailed view of the night sky whilst the reverse features just the brightest stars making it absolutely ideal for novice stargazers. Another innovation is that, instead of using a rivet to hold the apparatus together--covering up Polaris, the North Star--the map's outer frame holds the star wheel in place, permitting an uninterrupted view of the entire night sky. This also means that the star wheel can be removed. Additional instructions and information about stars, constellations and binocular objects can be found on the back side of the frame. Simply turn a dial to match time and date and see what the sky looks like at any particular moment. However, the problem with most planisphere's is that the shape of constellation patterns near the horizon is different on the map than in the sky. For example, the constellation Scorpius (the Scorpion) is elongated on a typical planisphere whereas on the Global Mapping Planisphere the distortion has been greatly reduced by gradually increasing the map's scale in the north-south direction.
