The Kepler Telescope - AstroMedia
AstroMedia Cardboard kit for an astronomical telescope after Johannes Kepler
Two lenses instead of one
Johannes Kepler further developed and improved the Galilean telescope. Instead of only one converging lens, he used two and thus made much higher magnifications possible. The upside-down image does not interfere with celestial observations, which is why almost all refracting telescopes are still built according to this design principle today. Thanks to the additional field lens, it has an amazingly large, bright image at ten times magnification. During the day, the Kepler telescope can also be used to observe sunspots.ATTENTION: For this you absolutely need a safe solar filter, e.g. AstroSolarTM solar filter foil from Baader Planetarium. See also "The solar telescope".
Tip: The performance of the telescope can be further improved by reducing the aperture of the objective lens with a round aperture. The image will then be less bright, but sharper.
For teachers and pupils
The Kepler telescope is easy to build and is an excellent teaching aid for secondary schools. Like all other astro materials, it can also be used for other group and project work on astronomy and physics.
