Lenses and glasses were already known in the mid-century XIV. However, only in 1608 the Dutch scientist Hans Lippershey has built the first telescope. Two years later, Galileo Galilei applied this tool to astronomy.

This project enables you to build a multi-element, Galilean-style telescope but as him, you’ll need to find out the focal length, the distance between lenses to its focus. The image will be blurry until you find out its focal point, by moving the eyepiece tube out. You will reach a point where the object comes out focused and magnified.
