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 dustfree 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

department. If your telescope is in need of internal cleaning, please call the factory

for a return authorization number and price quote.
