This map is a circular projection of the sky centered on the north celestial pole. Near the center of the map the constellations are not distorted, but at the edges (near the southern horizon), they are. Below are 16 pictures of the sky taken from Janice VanCleave's Constellations for Every Kid. They show how the constellations actually look in each direction in spring, summer, autumn and winter. The exercise is to correctly identify these 25 objects for binoculars or small telescopes by referring to the circular map. If you are going to memorize them, learn them in the order of the numbers. Numbers 1-12 are essential, they are all very good in binoculars. The last 13 mostly require a small telescope.
