Caring for and cleaning your telescope

To ensure your telescope performs at its best, regular maintenance of 

your telescope is recommended. 
Remember to replace the dust cap over the end of the telescope 

whenever it is not in use. This will prevent dust from settling on the 

mirror or lens surface. 
You must take care when cleaning the mirror or lens surface, and to 

only do so with the appropriate cleaning tools. We recommend using a 

combination of the following: 
•  A soft brush made from camel hair
•  A can of pressurized air to remove dust
•  Optical cleaning solution and a soft cloth
•  Special lens paper
If dust has built up on the optics, remove it with a brush or a 

can or pressurized air. Spray at an angle to the glass surface for 

approximately two to four seconds. Then, use an optical cleaning 

solution and a soft cloth to remove any remaining debris. Low pressure 

strokes should go from the center of the lens or mirror to the outer 

portion. Ensure that you do not rub in circles.
You can use a commercially made lens cleaner or mix your own.  

A good cleaning solution is isopropyl alcohol (60%) mixed with distilled 

water (40%). 
Clean the eyepieces with the special lens paper. Handle the eyepieces 

with care and avoid touching the optical surface.
You may experience dew build-up on the optics of your telescope 

during an observing session. You must remove the dew to continue 

observing. You can do so by using a hair dryer on low setting or by 

pointing the telescope downwards until the dew evaporates.
If moisture condenses on the inside of the optics, remove the 

accessories from the telescope. Place the telescope in a dust-free 

environment and point it downwards. This will remove the moisture 

from the telescope tube.
