While your telescope requires little maintenance, there are a few things to 
remember that will ensure your telescope performs at its best.

CARE AND CLEANING OF THE OPTICS

Occasionally, dust and/or moisture may build up on the objective lens of your 
telescope. Special care should be taken when cleaning any instrument so as 
not to damage the optics.

If dust has built up on the lens, remove it with a brush (made of camel’s hair) 
or with a can of pressurized air. Spray at an angle to the lens for approximately 
two to four seconds. Next, use an optical cleaning solution and white tissue 
paper to remove any remaining debris. Apply the solution to the tissue and 
apply the tissue paper to the lens. Low pressure strokes should go from the 
center of the corrector to the outer portion. Do NOT rub in circles!

You can use a commercially made lens cleaner or mix your own. A good 
cleaning solution is isopropyl alcohol mixed with distilled water. The solution 
should be 60% isopropyl alcohol and 40% distilled water. Or, liquid dish soap 
diluted with water (a couple of drops per one quart of water) can be used.

Occasionally, you may experience dew build-up on the lens of your telescope 
during an observing session. If you want to continue observing, the dew 
must be removed, either with a hair dryer (on low setting) or by pointing the 
telescope at the ground until the dew has evaporated.

If moisture condenses on the inside of the lens, remove the accessories from 
the rear cell of the telescope. Place the telescope in a dust-free environment 
and point it down. This will remove the moisture from the telescope tube.
To minimize the need to clean your telescope, replace all lens covers once you 
have finished using it. Since the rear cell is NOT sealed, the cover should be 
placed over the opening when not in use. This will prevent contaminants from 
entering the optical tube.
