Care and Maintenence
Your telescope is a precision optical instrument designed for a lifetime of rewarding viewing. It
will rarely, if ever, require factory servicing or maintenance. Follow these guidelines to keep your
telescope in the best condition:
As with any quality instrument, lens or mirror surfaces should be cleaned as infrequently as
possible. Telescope optics should be cleaned only when absolutely necessary. In all cases avoid
touching any mirror surface. A little dust on the surface of a mirror or lens causes negligible loss
of performance and should not be considered reason to clean the surface. When lens or mirror
cleaning does become necessary, use a camel’s hair brush or compressed air gently to remove
dust. If the telescope’s dust cover is replaced after each observing session, cleaning of the optics
will rarely be required.
Fingerprints and organic materials on the lens or mirror 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.
DO NOT
use a commercial photographic lens cleaner.
