CARE AND CLEANING OF THE OPTICS
Occasionally, dust and/or moisture may build up on the lens of your spotting scope. Special care
should be taken when cleaning any optical instrument so as not to damage the optics.
If dust has built up on the lens, remove the dust with a camel’s hair brush or a can of pressurized
air. Spray at an angle to the lens for approximately 2 to 4 seconds. Then use an optical cleaning
solution (available at most optical suppliers) and white tissue paper to remove any remaining
debris. Strokes should go from the center of the lens to the outer edge.
Do not rub in circles.
You can use 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.
Internal adjustments and cleaning should be done only by the Celestron repair department. If your
spotting scope is in need of internal cleaning, please contact the factory for service.
