AstroMedia: The Galileo telescope

AstroMedia: The Galileo telescope

As close to the sky as Galileo
Galileo Galilei did not invent the telescope, but he implemented a crucial improvement shortly after its invention in Holland. His telescope had a larger, outwardly curved converging lens as the objective (toward the observed object) and a smaller, inwardly curved diverging lens as the eyepiece (toward the eye). Even today, opera glasses are manufactured according to this principle.

The Galileo telescope from AstroMedia shows an upright image and has a tenfold magnification. During the day it can also be used to observe sunspots. See also "The Solar Telescope."

CAUTION: For this you absolutely need a safe solar filter, e.g. the AstroSolarTM solar filter foil from Baader Planetarium.

For teachers and students
The Galileo telescope is easy to build and is an excellent teaching aid for secondary schools. It can be used, just like all other astro materials, of course also in other group and project work on the subject of astronomy and physics.
