loosen the securing thumbscrews. The finder scope and
bracket can be removed together by loosening the thumb-
screw on the tube’s dovetail mount. Cover the front of the opti-
cal tube with the dust cover and the rear opening of the eye-
piece adapter with its cap. Now place the tube in the case’s
main compartment underneath the padded divider. The finder
scope and bracket can be placed on top of the divider as one
unit. The eyepiece and diagonal should be covered with their
caps and placed in the external compartments of the case.
Orion also offers an optional Padded Scope Case that will fit
the SkyView Pro Mount.

Storing

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, diagonals, and other
accessories can be kept in the included carrying case or in an
optional eyepiece case. Keep the dust cover on the front of
the telescope and cap the rear opening of the eyepiece
adapter. Also keep the finder scope caps on if you leave it
attached to the optical tube.

Cleaning the Tube

Your SkyView Pro 127mm 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 cleaner such as Windex or Formula 409.

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 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. On larger
lenses, clean only a small area at a time, using a fresh lens
tissue on each area. Never reuse tissues.
