Explore Scientific Galileoscope 50mm Refractor Kit — Build Your Own Educational Telescope

The Explore Scientific Galileoscope is a build-your-own 50mm refractor telescope kit — a hands-on STEM project that becomes a genuinely capable little telescope. You assemble the optical tube, focuser, and eyepiece yourself (no tools or glue required), learning how a telescope works as you go. When it's done you have a real 50mm f/10 refractor for exploring the Moon and planets.

Who it's for
Students, families, classrooms, and curious beginners who want to learn how telescopes work while building one. Shopping for a young stargazer? See our parent's guide to kids' telescopes.

• Build-it-yourself kit: assemble a working refractor with no tools or adhesives.
• Real 50mm optics: 500mm focal length (f/10) for sharp lunar and planetary views.
• 25x and 50x: the included eyepiece gives 25x; add the Barlow for 50x.
• STEM learning: teaches optics and telescope design hands-on.
• Tripod-ready: attaches to a standard photo tripod for steady viewing.

What you'll see
At 25x-50x the Galileoscope shows the Moon's craters and mountains, the phases of Venus, Jupiter's four bright moons, and the brightest star clusters — the same sights that amazed Galileo four centuries ago.

Is it hard to assemble?
No — it snaps together with no tools or glue, and the process is part of the learning experience for kids and adults alike.

Is it a real telescope?
Yes. Once built it's a functional 50mm refractor that shows the Moon, planets, and bright clusters.

Does it need a tripod?
For steady views, mount it on a standard photo tripod — highly recommended, especially for kids.

What age is it good for?
It's a great supervised project for school-age children and a fun intro to optics for all ages.
