Prof. Iadevaia Shows a Safe Method to View the Sun with Binoculars

Prof. Iadevaia shows how to use a pair of binoculars and a tripod to view the Sun. With the upcoming Solar Eclipse and transit of Venus, this method will work very nicely. Never look directly at the Sun with either a telescope or binoculars useless the appropriate filters are used. This method is a projection method and is very safe.
