A telescope component is an essential part of any telescope. The most common components are the LENS, PRISM, and eyepiece LENS. The LENS is a curved piece of glass that helps to focus light and create an image. The PRISM is a triangular-shaped piece of glass that helps to refract light and create a spectrum of colors. The eyepiece LENS is a small LENS that magnifies the image created by the other components. All three components work together to create a clear image for the observer.
