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 StarMax’s front meniscus lens or exposed
lenses of your eyepieces or finder scope. Never use regular
glass cleaner or cleaning fluid designed for eyeglasses.
Before cleaning with fluid and tissue, however, 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 finger-
prints and smudges may be removed using this method. Use
caution; rubbing too hard may scratch the lens. For the large
surface of the meniscus lens, clean only a small area at a
time, using a fresh lens tissue on each area. Never reuse tis-
sues.
