The Galilean Telescope - AstroMedia
AstroMedia Cardboard kit for a telescope that roughly corresponds to the telescope that the great Italian natural scientist Galileo Galilei was the first to point at the night sky at the beginning of the 17th century.
As close to the sky as Galileo
Galileo Galilei did not invent the telescope, but shortly after its invention in Holland he made a decisive improvement. His telescope had a larger, outwardly curved converging lens as an objective (towards the observed object) and a smaller, inwardly curved diverging lens as an eyepiece (towards the eye). Even today, opera glasses are made 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".
ATTENTION: For this you absolutely need a safe solar filter, e.g. the AstroSolarTM solar filter foil from Baader Planetarium.
For teachers and pupils
The Galileo telescope is easy to build and is ideal as teaching material at secondary schools. Like all other astro materials, it can also be used for other group and project work on astronomy and physics.
