care and Maintenance
If you give your telescope reasonable care, it will last a life-
time. Store it in a clean, dry, dust-free place, safe from rapid
changes in temperature and humidity. Do not store the tele-
scope outdoors, although storage in a garage or shed is OK.
Keep the dust caps and covers on when not in use.
cleaning lenses
Any quality optical lens cleaning tissue and optical lens clean-
ing fluid specifically designed for multi-coated optics can be
used to clean the exterior lens surfaces of the GoScope’s
objective lens, eyepiece, and reflex sight. Never use regular
glass cleaner or cleaning fluid designed for eyeglasses. Before
cleaning with fluid and tissue, blow any loose particles off the
lens with a blower bulb or compressed air. 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. For the large surface of the objective
lens, clean only a small area at a time, using a fresh lens tis-
sue on each area. Never reuse tissues.
