Description

A star finder (also known as a planisphere) is a circular map with an overlay that turns to show – through an opening in the overlay – the region of the sky that is visible for a specified time, date and location. It is an incredibly useful tool for orienting yourself in the night sky, for identifying constellations, and for planning your stargazing night.

The way a star finder works is simple. The days and months of the year are shown around the edge of a circular base, and the hours of the day are displayed around the overlay. By turning the overlay to line up the time of your observations with the date, the portion o the sky that is visible will appear through the opening in the overlay. All that remains is to hold the star finder over your head and orient it with respect to North.
