cleaning the tube
Your SkyView Pro 150mm EQ telescope 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 tele‑
scope. Smudges on the tube can be wiped off with a soft cloth
and a household cleaning fluid.
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 telescope's meniscus lens or the exposed
lenses of your eyepieces and finder scope. Never use regu‑
lar 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. On larger
lenses, clean only a small area at a time, using a fresh lens
tissue on each area. Never reuse tissues.
