What Are the Benefits of a Small Refractor?

Two types of telescopes are commonly used for basic observing. Reflecting telescopes use a system of mirrors to gather and focus light into an image, while refracting telescopes use lenses. Both models have advantages, but when it comes to small telescopes for backyard viewing, refractors tend to be more versatile, durable and easy to use.
  1. Durability

    • Because refracting telescopes contain sturdy glass lenses and not fragile mirrors, they are less prone to damage or breakage during transport to and from the observing site. Their durability also appeals to households with children, pets and other conditions that may threaten the longevity of valuable equipment. Refracting telescopes prove much more resistant to damage from rain, wind and other elements because their optical system is completely enclosed within the tube of the telescope.

    Maintenance

    • While the mirrors of a reflector often need careful cleaning and sometimes require recoating, the glass lenses of a refractor typically only need a quick, occasional swipe with a cleaning cloth to keep them free of dust and other obstructive debris. And, because their lenses remain fixed within the tube of the telescope, they don't need frequent realignment or recalibration.

    Image Quality

    • Small refractors are known for their ability to provide clear, sharp images, which rank as especially important when observing close together stars, such as those in a cluster or binary system, or when trying to view the details of the moon and nearby planets. For this reason, refractors have fans among birdwatchers and people looking for a telescope they can also use during the day. The high-quality images refractors provide also make them an appropriate choice for astrophotography.

    Ease of Use

    • The design of a small refracting telescope is simple, with lenses set up in a linear fashion to gather and focus light into the viewing eyepiece located directly at the end of the barrel. This sleek design makes it easy to maneuver, aim and find objects. The low-to-the-ground position of the eyepiece also makes observing more accessible and enjoyable for children or people who must remain seated while using the telescope.
