Refractor Telescopes

Whether you're purchasing your first telescope or looking to upgrade, you can find a range of high-quality refractor telescopes. Refracting telescopes use a lens as their objective to form an image and were originally used in astronomical telescopes and spyglasses. While they have been superseded by reflecting telescopes for most research purposes, they are a great option for those interested in both celestial and terrestrial observations.

Celestial Viewing

While refractor telescopes have small apertures and may be poor for viewing distant galaxies and nebulae, they are perfect for viewing stars, the moon and other planets. They work well in urban settings as they provide better contrast than reflecting telescopes, even if you're staring into night skies with lots of light pollution. If your main purpose is astronomical viewing, rather than terrestrial viewing, be sure to look for astronomical refractor telescopes.

Terrestrial Viewing

One of the main advantages of a refracting telescope over a reflecting model is that it can be used for land-viewing as well. It's important to keep in mind that images will be mirrored, although this shouldn't be a hindrance for most users and can be corrected using erected prisms if required.

Low Maintenance

Another advantage of refractor telescopes is their low-maintenance requirements, which are due to their closed tube designs. The optics inside are kept better protected and any image degrading currents are prevented from entering. They are also easy to set up and use, making them great for quick viewing experiences.

Calculating Magnifications

A refracting telescope's magnification is calculated by dividing the focal length of the objective lens by that of the eyepiece. The bigger the diameter of your lens, the more detail that will be available for observation. Search for 50mm refractor telescopes if that's what your budget allows or look for 150mm refractor telescopes if you want a superior viewing experience.
