Eclipse glasses: a safe way to observe the Sun
The only safe way to observe the SUn with the naked eyes is through special eclipse glasses. These eclipse glasses are not only perfect for watching solar eclipses, but also when there are large sunspots on the Sun.

Please carefully read the instructions and recommendations! Looking at the Sun without the right protection or with damaged protection can b very harmful to your eyes and cause blindness.

Please note: we have a (Dutch) brochure called Veilig zonnekijken (Safely observing the Sun) which you can download for free.

To watch the Sun in more detail it is best to visit an (amateur) observatory or astronomy club nearby. They have telescopes with special filters and the knowledge to tell you everything about our star!
