The multitude of stars in the sky can be confusing, but the Collins Star Finder Pack gives you everything you need to identify the stars. The star finder is accompanies by a 32-page booklet explaining the best way to observe the night sky and also shows the positions of the planets for the next five years. The large star finder is simple to use: just dial in the date and time by rotating the inner plastic disk until it lines up with the relevant day of the year calibrated on the outer ring. The portion of sky shown on the planisphere will show the arrangement of the stars above you. The color wall chart contains a map of the night sky, plus details of all the other features you can find-galaxies, comets, asteroids, and planets. It also contains a seasonal guide on how to find your way around the night sky, allowing even beginners to quickly understand where to look for Polaris or the Pleisades.
