We recommend storing all equipment in an air tight container with desiccate packages
to remove unwanted humidity from the air.  Never leave the telescope in a humid
environment, and avoid leaving the scope in a hot heated environment.  If not properly
stored, it is possible for the scope to develop mildew growth or other preventable
conditions.  Be careful after a night of observing when conditions might leave dew on
the lens, and allow the scope to air dry in a room temperature environment before storing
the telescope.

If the front lens surface becomes dusty, smeared, shows fingerprints, or any other
surface build up, the following steps can be taken to clean the lens.  First, gently blow
away any surface dust or particles with a clean air blower (canned or compressed air is
not recommended).  Second, use a photographic quality optical cleaning solution and
cloths to gently wipe the surface clean.  A clean cloth should be used every time that
cleaning is needed.  With proper care, and protection, cleaning should rarely be needed.

The Zenithstar has a beautiful high gloss anodized finish that can be easily smudged
with fingerprints; however this will not harm the finish.  A slightly dampened clean soft
cloth with plain water should be enough to clean the surface.  Please avoid any harsh
chemical cleaners or organic solvents like benzene, alcohol, etc, as these may ruin the
finish.

Caution!  Never directly view the Sun with your telescope!

Do not aim your telescope at the Sun without a front mounted high

quality professionally manufactured solar filter.  Viewing the Sun without

the proper protection may result in permanent severe damage to your

eyes, and even cause blindness.  Contact your Authorized WO Dealer

if you are interested in purchasing a compatible and proper solar filter.

Always place the telescope on a flat surface, to prevent it from falling

and injuring yourself or others.

Never use the telescope in the rain or in conditions where it may get

wet.  The telescope is not designed to be waterproof.  If the telescope

accidentally gets caught in the rain, immediately wipe off all water

using a clean dry soft cloth.  If the telescope gets totally soaked in

water, immediately contact your Authorized WO Dealer for service

instructions.

Do not disassemble or attempt to repair your telescope without a

written authorization from William Optics Corp., as this violates the

warranty terms under the limited product warranty, and negates any

guarantee.

Caution for Safety

The focuser's tension can be adjusted using a 2.5mm allen wrench if needed.

The Focuser Lock Thumb Screw is used to tighten down the focuser's travel
while in use to prevent the focuser from accidentally moving. This is most
likely when the telescope is pointed upwards and the additional weight of
large eyepieces or photography equipment may make the focuser move on
its own.

Please consult with your consult with your Authorized WO Dealer or WO
directly if you have any questions before adjusting the focuser.
