Types of Telescopes
Refractor Telescopes
Refractor telescopes use lenses to gather and focus light. They are known for their excellent image quality and sharpness. The objective lens at the front of the telescope collects light and focuses it to a point, where an eyepiece magnifies the image for observation. Refractor telescopes are generally low maintenance and provide clear, high-contrast views of celestial objects.
Reflecting Telescopes
Reflecting telescopes use mirrors instead of lenses to gather and focus light. These telescopes have a concave primary mirror that collects and reflects light to a secondary mirror, which then directs the light towards an eyepiece for observation. Reflecting telescopes tend to provide a larger aperture at a more affordable price than refractor telescopes, making them popular among astronomers.
Compound Telescopes
Compound telescopes, also known as catadioptric telescopes, combine both lenses and mirrors to gather and focus light. They are a hybrid design that offers a compact and versatile option for astronomers. Compound telescopes often feature a corrector lens at the front to improve image quality and a combination of mirrors and lenses to direct the light towards the eyepiece. This design allows for a longer focal length in a more portable package.
