MAINTENANCE AND SERVICE
General maintenance instructions
This telescope is considered a precision optical instrument that will give
you many years of enjoyment. As long as you give your telescope the care
and attention due a precision instrument, you will very rarely need factory
service or other appropriate maintenance.
IMPORTANT NOTE:
Always strictly adhere to the instructions given here in case of possible
maintenance. Since this is a sensitive opto-mechanical instrument, even
the smallest steps performed incorrectly can cause irreparable damage to
the device! The manufacturer accepts no liability for damage resulting from
improper handling or maintenance!
The following points should be noted:
A Avoid cleaning the telescope optics too frequently. A little dust on the
front of your telescope's lens, or on the mirror surface, causes virtually
no reduction in imaging quality, and so a little dust should not cause you
to constantly clean the optical surfaces.
b. Only if absolutely necessary, the jam on optical surfaces can be remo-
ved with gentle movements of a fine photo brush. You can also blow the
dust away with a small bellows. However, do not use any photographic
lens cleaners under any circumstances!
c. Organic soiling (fingerprints, etc.) on optical surfaces is best removed
with a cleaning fluid consisting of three parts distilled water and one
part isopropyl alcohol. You may add a small drop of biodegradable dish-
washing liquid per half litre of cleaning liquid. Also, use only soft, white
cosmetic wipes, make short, careful wiping motions, and change wipes
as often as possible.
Attention:
Do not use fragrance impregnated, dyed or lotion soaked cloths as
they will damage your optics.
D Never, for any reason, remove the optics from their mount; not even to
clean them or for any other reason. You would probably not be able to
reinsert them at the exact position and risk a serious degradation of the
optical performance of your telescope. In such cases, Bresser accepts
no liability whatsoever for any damage incurred.
e If your telescope is used outside during a humid night, dew may settle
on the surface of the telescope. Normally, such wetness does not cause
any damage, but it is strongly recommended to dry the telescope with a
suitable cloth each time before storing it. However, never wipe the optical
surfaces dry! Instead, leave the telescope in a warm room for a while
so that the damp optical surfaces can dry by themselves. Wait until the
telescope is completely dry before repacking it.
f. Never leave your telescope in a locked car on hot summer days.
Excessive temperatures can affect the internal lubrication.
