Best Selling Telescope Refractors
A refractor telescope is a type of telescope that uses lenses to refract, or bend, light to create an image. Refractor telescopes are typically used for viewing objects in the night sky, such as planets, stars, and galaxies. They are also used for observing terrestrial objects, such as birds and wildlife.
Refractor telescopes are available in a variety of sizes and prices, making them a good option for both beginners and experienced astronomers. Some of the features to consider when choosing a refractor telescope include the aperture, focal length, and mount.

Aperture
The aperture of a telescope is the diameter of the lens or mirror that collects light. The larger the aperture, the more light the telescope can collect, and the brighter and more detailed the images will be. Refractor telescopes typically have apertures ranging from 50mm to 150mm.
Focal Length
The focal length of a telescope is the distance from the lens or mirror to the focal point, where the image is formed. The focal length of a refractor telescope is typically expressed in millimeters. The longer the focal length, the more magnification the telescope will provide.
Mount
The mount of a telescope is the structure that supports the telescope and allows it to be pointed at different objects in the sky. There are a variety of different mounts available, each with its own advantages and disadvantages. Some of the most common types of mounts include the altazimuth mount, the equatorial mount, and the Dobsonian mount.
Advantages of Refractor Telescopes
Refractor telescopes offer a number of advantages over other types of telescopes, including:
- They are relatively compact and lightweight, making them easy to transport.
- They provide sharp, clear images with good contrast.
- They are relatively easy to use, even for beginners.
Disadvantages of Refractor Telescopes
Refractor telescopes also have a few disadvantages, including:
- They can be more expensive than other types of telescopes.
- They are more susceptible to chromatic aberration than other types of telescopes.
- They cannot be used for astrophotography without a special adapter.
Conclusion
Refractor telescopes are a good option for both beginners and experienced astronomers. They offer a number of advantages over other types of telescopes, but they also have a few disadvantages. If you are considering purchasing a refractor telescope, be sure to do your research to find the best telescope for your needs.
