CARING FOR YOUR TELESCOPE
Your DSX telescope is a precision optical instrument designed to yield a lifetime of rewarding
observations. Given the care and respect due any precision instrument, your telescope will
rarely, if ever, require factory servicing. Maintenance guidelines include:
a. Avoid cleaning the telescope’s optics: a little dust on the front surface of the telescope’s
correcting lens causes virtually no degradation of image quality and should not be
considered reason to clean the lens.
b. When absolutely necessary, dust on the front lens should be removed with gentle strokes
of a camel hair brush or 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 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 telescope. Batteries left in the telescope for
prolonged periods may leak, causing damage to the telescope’s electronic circuitry.
f. Do not leave the telescope inside a sealed car on a warm summer day; excessive
ambient temperatures can damage the telescope’s internal lubrication and electronic
circuitry.
