Kit to build an astronomical telescope as described by Johannes Kepler

Englische Version des Artikels "Das Kepler Teleskop" 111.KEP

Two lenses instead of one

Johannes Kepler further developed and improved the Galilean telescope. Instead of only one collecting lens, he used two and this 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 based on 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 by the Baader Planetarium.
Tip: The performance of the telescope can be further improved by reducing the opening 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 instrument for secondary schools. Like all other astro materials, it can also be used for other group and project work on astronomy and Physics.

Tip

With the inexpensive photo tripod adapter, the telescope can be mounted on any standard photo or video stand. This prevents the small trembling movements of the hand and the telescope unfolds its full power.
