WILLIAM OPTICS WIFD REDCAT 61 Refractor Telescope
Warning
Never aim your telescope or finder scope at the Sun without proper Solar
filters installed on the front of the telescope. Doing so for even a moment
may permanently damage your vision. Proper Solar filters consist of filters
made by reputable manufacturers, designed to fit tightly over the front of the
dew shield. Solar the ye piece filters are not considered safe, and should not
be used. With proper front mounted Solar filters, the telescope will not be
harmed by viewing the Sun.

NOTE
We are utilizing a unique Petzval design featuring four optical elements in
the William Optics (WO) Cat series telescopes.This design incorporates the use
of high-quality FPL-53 glass for superior optical performance. Before storing
your telescope, it is crucial to allow it sufficient time to acclimatize to
room temperature. Please ensure that the telescope is thoroughly dry, free of
dew or moisture, before storing. This ensures the safety and longevity of the
telescope’s components. Always store the telescope in a consistent-temperature
and dry environment to prevent any potential damage to the optical elements.
Remember to leave the tube uncovered and opened during the acclimatization
period. As always, taking appropriate care of your telescope will ensure its
optimal performance and extend its lifespan.
