solar filter
Blocks harmful rays
A solar filter is a device that blocks most sunlight, allowing safe observation of the sun through telescopes, binoculars, or cameras.
Without proper filtration, viewing the sun directly causes permanent eye damage.
Solar filters reduce light intensity by a factor of 100,000 or more: Make sure your solar filter is securely attached before the eclipse.
