Astroval : Sun watching


Welcome to the astronomic Observatory AstroVal!

Come and safely watch the sun at AstroVal through our two astronomic telescopes equipped with sun watching filters.

Each of them will show you different aspects of the Sun.With our helioscope you can see the surface of the Sun, which can show distinctive dark zones named solar spots. With our "H-alpha" telescope you can see the atmoshpere around the Sun and its gigantic protrusions.

The Sun is a living star, which means that the number and size of spots and eruptions changes all the time, making every observation different.
