With this kit you can build a small telescope with 6.5x magnification. It is a Galileo Telescope with an original AstroSolarTM filter film that allows for direct observation of the Sun and solar eclipses. Without the filter you can project a 2” picture of the sun onto a white piece of paper, or just use it to observe nature or the stars.

In 1609, when Galileo Galilei presented the world his improvement of the telescope he had invented a year earlier, stargazing as we know it today was born. His discoveries were a scientific sensation, but they initially concentrated on lunar craters, crescent phases of Venus and moons around Jupiter. The Sun came into focus a little later, often with grave consequences for its observers who did not protect their eyes.

With a few elements, such as an open cardboard box, a white sheet and a little bit of skill, you can also build a solar projector and observe the sun together with others. The building instructions tell you exactly how it works.

Detailed assembly instructions

Made in Germany

Needed for assembly:

a firm and flat working surface, useful is a cutting mat
a sharp craft knife or a scalpel

a good solvent-based universal glue

Supervision by adults:
Children under the age of 14 should use the kit under adult supervision to avoid risks due to improper handling.

Take care with small parts:
Choking hazard! Keep small parts out of the reach of small children.

Safe use:
Check the BAADER AstroSolar® safety filter for damage such as abrasions, scratches or other safety-relevant influences before each use. Do not continue to use damaged film.
If the film is damaged or scratched, the telescope must no longer be used for solar observation as it no longer provides adequate protection and poses a high health risk.

Risk of injury:
Take particular care when handling pointed and sharp parts! Use sharp tools carefully and take suitable safety measures to avoid injury if necessary.

Use of adhesive:
When using adhesive, follow the manufacturer’s safety instructions. Work in well-ventilated areas and avoid contact with skin or eyes.

Intended use:
The BAADER AstroSolar® safety filter must not be used for naked-eye observation or for making sunglasses without additional protection.
The kit should be used in accordance with the enclosed instructions. Independent modifications may impair the functionality and safety of the model built.
