Galileoscope Telescope
No matter where you live, with this easy-to-assemble, 50-mm (2-inch) diameter, 25- to 50-power achromatic refractor, you can see the celestial wonders that Galileo Galilei first glimpsed 400 years ago and that still delight stargazers today. These include lunar craters and mountains, four moons circling Jupiter, the phases of Venus, Saturn's rings, and countless stars invisible to the unaided eye.  The Galileoscope comes as a kit with simple instructions for no-tools assembly in 5 minutes or less. It is well-built and can be assembled and disassembled many times with little wear and tear.  Its achromatic optics include a 50-mm-diameter objective lens of focal length 500 mm, an eyepiece of focal length 20 mm (magnification 25x), and a 2x Barlow lens (yielding 50x when used with the supplied eyepiece). The Galileoscope accepts almost any optical accessory that has a standard 1-inch (31-mm) barrel, and it attaches to virtually every tripod made or distributed anywhere in the world.
