Galileoscope: Build Your Own Refractor Telescope

The Galileoscope is a build-it-yourself refractor telescope kit that lets students, families and new astronomers discover the universe the way Galileo did more than 400 years ago. Developed as an educational telescope, the Galileoscope teaches how lenses form images and magnify distant objects while delivering real, rewarding views of the night sky.

Once assembled, the Galileoscope shows the craters and mountains of the Moon, the four largest moons of Jupiter, the rings of Saturn and the phases of Venus, the same discoveries that changed our understanding of the cosmos. It is a popular STEM telescope kit for classrooms, science fairs, homeschool programs and astronomy outreach, and it makes an inspiring gift for curious kids and adults.

This collection includes the Galileoscope telescope kit, a dedicated tripod for steady views, and a solar filter and sun shade kit that turns the Galileoscope into a safe solar telescope for observing sunspots. Assembly requires no tools and takes only a few minutes, making it an ideal hands-on learning project. With the Galileoscope, learning optics and astronomy becomes an unforgettable experience.
