Care & Maintenance

Additional Precautions

Minimize large fluctuation in temperature 

around  your  telescope.  When  the 

telescope is brought out from a warm 

room to colder air, dew may form.

Store  the  telescope  in  a  cold  dry 

environment. Any dew should be removed 

by blowing it with a hair dryer with the 

heat element turned off, which means the 

air will be at room temperature. This flow 

of room temperature air will dry the dew 

and not leave a residue. Additionally, it is 

a good idea to store the telescope with a 

drying agent near the objective to prevent 

moisture issues.

NEVER  USE ALCOHOL  TO  CLEAN 

THE LENS. IT WILL DESTROY THE 

COATING.

Under  no  circumstances  should  the 

lenses be disassembled. The lenses have 

been properly aligned and set in place by 

a skilled optical technician with special 

tools. Movement, removal or disassembly 

of the lenses will void any warranty on the 

tube assembly.

▼Optical Axis

Before shipment, the optical axis of your 

telescope has been precisely adjusted 

and in normal use it should not require 

adjustment.  On  occasion,  however, 

damage  or  rough  handling  during 

transport may cause alignment issues.

If there is an abnormal star image visible 

with your telescope, immediately contact 

your local distributor.

▼Care for the Lens

 

If the front lens of the objective has dust 

or dirt particles on it, use a large hand-

powered blower to remove the particles. 

Under no circumstances should dust be 

removed by any other means. Rubbing 

the surface will cause scratches. If the 

lens must be cleaned, be certain that all 

dust and particles have been removed by 

using a blower.

Then  using  cotton  swabs  slightly 

moistened with telescope lens cleaner, 

dab the surface, changing cotton swabs 

often until the objective is cleaned. 

If any questions arise during this process, 

immediately contact your local distributor 

for help. Under no circumstances should 

the surface ever be rubbed.

REMEMBER, DO NOT USE ANY FORM 

OF  CANNED AIR  TO  REMOVE  THE 

PARTICLES.

Canned air is very cold and could harm 

the front lens of the objective. Be certain 

that  the  dew  cap  is  removed  before 

attempting to clean the objective. Use 

the procedure above, if the front and rear 

surfaces of the objective must be cleaned.
