Lab: Observation Projects Telescopes and the Sun Background: Group : __________________________ _________________________________ Telescopes gather more light than your eye can, making faint objects visible. The telescope you will be working with today does this by using glass lenses to focus the light as it refracts through the lenses. Refracting Telescopes: The light refracts (bends) as it goes through a glass lens. The light is then straightened out by an eyepiece lens. Advantages: simple, beginner telescopes are cheaper Limitations: imperfect glass, glass filters out some wavelengths
