WARNING: Never look at the sun with your telescope without a
professionally made solar filter. Permanent eye damage or blindness
could result. Eye damage is often painless, so there is no warning until
it is too late. Children should not be allowed to handle the telescope.
Avoid using the type of solar filter that screws into an eyepiece. They
are susceptible to cracking under the intense heat that builds up near
the focus point, and could cause severe retinal damage. se only the
type of solar filter that covers the front of the telescope. Also, be sure to
leave the cover caps on the finder scope when solar observing. Better
yet, remove the finder scope altogether when viewing the sun.
