Safely Viewing the Total Solar Eclipse
With the exception of the very brief total phase of a total solar eclipse, when the Moon completely blocks the Sun’s bright face, it is not safe to look directly at the Sun unless you are using eye protection specifically for solar viewing.
Do not view any part of the bright Sun through a camera lens, binoculars, or a telescope without a special-purpose solar filter secured over the secured over the front of the instrument as this will instantly cause severe eye injury.
Homemade filters or ordinary sunglasses, even very dark ones, are not safe for looking at the sun. They transmit thousands of times too much sunlight and could damage the eyes.
