10. 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.
Small components like eyepieces and other accessories
should be kept in a protective box or storage case. Keep the
dust cover on the front of the telescope when not in use.
Your SkyView Pro 80mm ED EQ requires very little mechanical
maintenance. The optical tube is aluminum and has a smooth
painted finish that is fairly scratch-resistant. If a scratch does
appear on the tube, it will not harm the telescope. Smudges
on the tube can be wiped off with a soft cloth and a household
surface cleaner.
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 exposed lenses of your telescope’s objec-
tive lens, eyepieces, or finder scope. 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. On larger lenses, clean only a
small area at a time, using a fresh lens tissue on each area.
Never reuse tissues.
