Protect your eyes

Observers must be very careful while viewing the solar eclipse. Our advice is to never look at the Sun with the naked eye.For safety, you must always use sunglasses, telescopes and binoculars with special filters. Never use these equipments without protection as the Sun's ultraviolet and infrared light may harm your eyes or cause blindness if you look at the Sun directly.
