CARE AND CLEANING OF THE TELESCOPE
While your telescope requires little maintenance, there are a few things to remember that will ensure your telescope performs at its
best. Occasionally, dust and/or moisture may build up on the objective lens. Special care should be taken when cleaning any instrument
so as not to damage the optics.
If dust has built up on the optics, follow these steps, in order, to clean your scope:
1. Use a camel hair brush to gently remove the larger particles.
2. Use a photographer’s squeeze bulb to blow away any loose debris. You can also use a can of compressed air, such as those sold for
cleaning computer keyboards, but you need to be careful. Avoid using cans that are almost empty and be sure to hold the air can vertically.
Failure to do this can result in the can spitting propellant out onto the optics. Hold the optical surface at an angle to the spray from the can
for approximately two to four seconds.
3. Use an optical cleaning solution of over-the-counter isopropyl alcohol and distilled water in a 50/50 mixture. Apply this solution to a white
unscented tissue, 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 in straight lines like spokes on a wheel. Do not rub in circles!
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 downward until the moisture evaporates.
To minimize the need to clean your telescope, replace all lens covers once you have fi nished using it. Since the telescope tubes are not
sealed, the covers should be placed over the openings when not in use. This will prevent contaminants from entering the tubes.
Internal adjustments and cleaning should be done only by the Celestron repair department. If your telescope is in need of internal clean-
ing, please call the factory for a return authorization number and price quote.
SAFETY INSTRUCTIONS
• There is a risk of explosion if the battery is replaced with an incorrect type.
• The included battery is not rechargeable.
• Only use the battery as originally intended to avoid a short circuit. Connecting the conductive material directly to the battery’s positive and
negative sides will cause a short circuit.
• Do not use a damaged battery.
• Do not store the battery in an extremely cold or hot environment. Doing so can reduce battery life.
• Remove batteries if drained or if product is to be left unused for a long time.
• When replacing the battery, refer to the instruction manual and ensure the positive and negative sides are oriented correctly.
• Do not put the battery in fi re.
• Dispose of the battery according to local regulations.
