TELESCOPE MAINTENANCE
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 optics, remove it with a brush (made of camel’s hair) or a can of pressurized air Spray at an angle
to the glass surface for approximately two to four seconds Then, use an optical cleaning solution and white tissue paper to
remove any remaining debris Apply the solution to the tissue and then apply the tissue paper to the optics Low pressure
strokes should go from the center of the lens (or mirror) 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 optics 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 optics, remove the accessories from 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 cells are NOT
sealed, the covers should be placed over the openings when not in use This will prevent contaminants from entering the
optical tube
Internal adjustments and cleaning should be done only by the Celestron repair department If your telescope is in need of
internal cleaning, please call the factory for a return authorization number and price quote
