POCKET STAR FINDER
This pocket-sized tool is great for taking outside to view the stars. It is made of flexible plastic--so weatherproof and durable--and measures only 5" diameter. This Star Finder is designed to use at 40 north and all mid-northern latitudes. Instructions are printed on the back of the Star Finder. Simply align the time of one wheel with the date on the other wheel for a view of the constellations that should be visible at that time. A piece of red plastic is included as a filter for your flashlight, to preserve your night vision.
