b.When absolutely necessary, dust on the mirror should be blown off with an ear syringe (available at any pharmacy). DO NOT use a commercial photographic lens cleaner.
c.Organic materials (e.g., fingerprints) on the front lens may be removed with a solution of 3 parts distilled water to 1 part isopropyl alcohol. You may also add 1 drop of biodegradable dishwashing soap per pint of solution. Use soft, white facial tissues and make short, gentle strokes. Change tissues often.
Caution: Do not use scented or lotioned tissues or damage could result
to the optics.
d. If the telescope is used outdoors on a humid night, water condensation on the telescope surfaces will probably result. While such condensation does not normally cause any damage to the telescope, it is recommended that the entire telescope be wiped down with a dry cloth before the telescope is packed away. Do not, however, wipe any of the optical surfaces. Rather, simply allow the telescope to sit for some time in the warm indoor air, so that the wet optical surfaces can dry unattended.
e. If your telescope is not to be used for an extended period, perhaps for one month or more, it is advisable to remove the batteries from the battery pack. Batteries left in the telescope for prolonged periods may leak, causing damage.
g. Do not leave your telescope inside a sealed car on a warm summer day; exces- sive ambient temperatures can damage the telescope’s internal lubrication
