will not harm the telescope. If you wish, you may apply some
auto touch-up paint to the scratch. Smudges on the tube can be
wiped off with a soft cloth and household cleaning fluid.
Cleaning Optics
Any quality optical lens cleaning tissue and optical lens cleaning
fluid specifically designed for multi-coated optics can be used
to clean the lenses of your telescope and eyepieces. Never
use regular glass cleaner or cleaning fluid designed for eye-
glasses. Before cleaning, remove any loose particles or dust
from the lens with a blower bulb or soft brush. Then apply some
cleaning fluid to a tissue, never directly on the optics. Wipe the
lens gently in a circular motion, then remove any excess fluid
with a fresh lens tissue. Oily fingerprints and smudges may be
removed using this method. Use caution; rubbing too hard may
scratch the lens. On larger lenses, clean only a small area at a
time, using a fresh lens tissue on each area. Never reuse tis-
sues.
When bringing the telescope inside after an evening’s viewing
it is normal for moisture to accumulate on the lenses due to
the change in temperature. We suggest leaving the telescope
and eyepieces uncovered overnight to allow the condensation
to evaporate.
