If you want a better view of birds, treetops, or even the night sky, you and your family can build your own simple telescope. Use this make-it-yourself device to explore the world, then check out these tips to keep track of what you see.
WHAT'S GOING ON?
Your telescope is a "refracting telescope," because it uses lenses to help gather more light than your eye could possibly do on its own. The scope uses two lenses to bend light, which makes an object appear closer than it really is. The size of the image produced by the telescope depends on the curvature of the lenses. Lenses with different curvatures will change the magnification of the telescope.
