Refractors

A refractor is a classic telescope design that uses a collection of lenses to gather and focus light. Explore Scientific’s broad selection of refracting telescopes includes apochromatic refractors ranging in aperture from 80mm to 165mm, achromatic telescopes perfect for astronomy outreach and beginner refractors from brands like National Geographic and Discovery that are great for backyard astronomy.
