Refractor telescopes, as opposed to reflector telescopes, use lenses as opposed to mirrors, respectively. They typically collect less light than reflector telescopes, making them ideal for daytime or land viewing, as you don’t need to try to collect the light of a far-off star to see it. They also typically have slightly clearer images than reflector telescopes.
Due to the different way the two telescopes work, they’re optimized for their intended purpose. Land viewing telescopes have three lenses to view the image and then turn it right side up. Celestial telescopes have two lenses plus their mirrors to collect more light, and the image is usually upside down (that doesn’t matter so much when you’re just looking at stars).
