Cleaning & Care
In general, the principle "less is more" applies to the cleaning of all optics!
Telescopes with a closed tube such as refractors and Schmidt-Cassegrains generally
do not need very much care. An occasional cleaning is all that is needed – and all the
less often if the telescope is stored carefully.
Over time, dust or moisture accumulates on the front lens. Great care is required to
avoid damaging the optics. If dust has settled on the lens, remove it with a camel hair
brush or with compressed air. Blow on the lens at a shallow angle for a few seconds.
For further removal of stuck dirt, use Optical Wonder Fluid from Baader Planetarium
and a soft cloth (Kleenex (!) – no other brand!) to remove any remaining residue.
Wipe from the centre of
the lens outwards. Do not
rub in circles! Never spray
the cleaning fluid onto the
lens! Otherwise liquid could
flow between the lenses of
a refractor or onto the back
of the Schmidt plate. Put
the liquid on a cloth and
then treat the lens with the
cloth.
Occasionally, dew condenses on the front lens or Schmidt plate during observation.
This can be removed with a hairdryer or by pointing the telescope at the ground. If
moisture condenses inside the telescope, remove the eyepiece holder and store the
telescope in a dust-free place with the objective lens pointing downwards. This will
eliminate the moisture in the tube.
Alternatively, we offer reusable desiccant that can be filled into small cloth bags and
pushed into the eyepiece holder to actively dry the inside of the telescope. Be careful
not to drop it into the telescope though!
To minimise the need for cleaning, always place the dust
covers on the lenses after using the telescope. Since the
eyepiece end of the telescope is open, always put the
plastic cap on. This prevents foreign objects from entering
the tube.
After a night of observation, always inspect the telescope
the next day to see if any residual moisture has remained on
the optical surfaces. If necessary, allow the telescope to air
open and only then close it dust-tight again.
