remove the optical tube from the mount. Make sure to have a 
firm grip on the tube as it releases from the mount. To place the 
optical tube in the case, the eyepiece, diagonal, finder scope 
and bracket must be removed from the tube. When remov‑
ing the eyepiece and diagonal, remember to first loosen the 
securing thumbscrews. The finder scope and bracket can be 
removed together by loosening the thumbscrew on the tube’s 
dovetail mount. Cover the front of the optical tube with the 
dust cover and the rear opening of the eyepiece 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 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.
