The Solar Viewers by Baader Planetarium are a high-quality product which is extremely well suited for naked-eye solar observations. The most common use-case for them is solar eclipses.
As the moon passes slowly in front of the sun, you can easily observe how the sun disappears behind it through the Solar Viewer. The spectacular event of a total solar eclipse itself, which usually lasts only for a few minutes, should then be enjoyed without the glasses and safely with the naked eye.
CE / ISO certified: conforms to and meets the transmission requirements for eye safety: EN ISO 12312-2:2015 – Instructions in four languages (English, German, French, Spanish) on the inner side of the solar viewer.
