WARNING!
Never use a Meade
®
Telescope to look at
the Sun! Looking at or near the Sun will
cause instant and irreversible damage to
your eye. Eye damage is often painless, so
there is no warning to the observer that
damage has occurred until it is too late. Do
not point the telescope or its viewfinder at or
near the Sun. Do not look through the
telescope or its viewfinder as it is moving.
Children should always have adult
supervision while observing.
