About This Product
A simple refracting telescope uses two lenses: a lens of longer focal length collects light from a distant object, and a lens of shorter focal length magnifies the image that it forms. Sliding one tube within the other changes the distance between the lenses and brings the image into focus. Students use such a telescope to study how lens combinations form images, and to view distant objects on the ground and in the sky.
