The SmartStar

®

 E mount or telescope is a 

precision instrument designed to yield a 
lifetime of rewarding applications. Given the 
care and respect due any precision 
instrument, your telescope will rarely require 
factory servicing or maintenance. 
Maintenance guidelines include: 

1. 

Using wet cloth to clean the mount 

and hand controller. Do not use the solvent. 
2. 

Leave the dust cap on while not 

operating the telescope. As with any quality 
instrument, lens or mirror surfaces should 
be cleaned as infrequently as possible. 
Front surface aluminized mirrors, in 
particular, should be cleaned only when 
absolutely necessary. In all cases avoid 
touching any mirror surface. A little dust on 
the surface of a mirror or lens causes 
negligible loss of performance and should 
not be considered reason to clean the 
surface. When lens or mirror cleaning does 
become necessary, use a camel’s hair 
brush or compressed air gently to remove 
dust.  
3. 

Organic materials (e.g., fingerprints) 

on the lens may be removed with a solution 
of 3 parts distilled water to 1 part isopropyl 
alcohol. Use soft, white facial tissues or 
cotton balls and make short, gentle strokes. 
Change tissues often. Do not use scented, 
colored, or lotioned tissues as damage 
could result to the optics. 
4. 

If your telescope is used outdoors on 

a humid night, telescope surfaces may 
accumulate water condensation. While such 
condensation does not normally cause any 
damage to the telescope, it is 
recommended that wait the entire telescope 
be dried before being packed away. Do not 
wipe any of the optical surfaces. In addition, 
the dust cap should not be placed back on 
to the optical tube until the telescope is 
thoroughly dry.  
5. 

If your telescope is not to be used 

for an extended period, perhaps for one 

month or more, it is advisable to remove the 
batteries from battery holder, if they are 
installed. Batteries left installed for 
prolonged periods may leak, causing 
damage to the telescope’s electronic 
circuitry. 
6. 

Do not leave your telescope 

outdoors on a warm day or inside a sealed 
car for an extended period of time. 
Excessive ambient temperatures can 
damage the telescope’s internal lubrication 
and electronic circuitry. 

When not in use, store the telescope in a 
cool, dry place. Do not expose the 
instrument to excessive heat or moisture. It 
is best to store the telescope in its original 
box with the altitude lock knob unlocked. If 
shipping the telescope, use the original box 
and packing material to protect the 
telescope during shipment. 

When transporting the telescope, take care 
not to bump or drop the instrument; this type 
of abuse can damage the optics or affect 
the GOTO tracking accuracy.  

The following suggestions may be helpful 
with operation of the SmartStar

®

 E mount or 

telescope. 

1. Verify that the power switch on the 

mount is in the ON position.  

2.  Verify that the hand controller cord is 

firmly connected to the HBX port on the 
mount, or switch the cord to the other 
HBX port.  

3.  Check the power source, which include: 

•  Using the battery? Are the batteries 

installed correctly? Are the batteries
