Whether you are gazing upon the desolate lunar surface features or enjoying terrestrial views, we have a refractor that’s perfect for you!

Modern refracting telescopes come in two basic styles: achromatic and apochromatic. Refractors often suffer from chromatic aberration, and each design reduces this aberration differently. Refractors can also be mounted on either an Equatorial or Altazimuth mount. This gives you a wide range of options to choose from when deciding what kind of telescope you need.

There are several characteristics you will need to consider when purchasing a telescope. The focal length is integral to determining how far you will be able to see out of your telescope. It also helps determine your telescope’s focal ratio and field of view. Aperture is important to look at also because it determines how much light your OTA will capture. All these factors together make each telescope unique, each providing a different viewing experience. Looking at telescope spec can be daunting, that is why we at High Point are here to help you make the best selection based on your aspirations and budget.
