Improper cleaning of the aluminized mirrors can scratch their
coatings, so one should use blower bulb or special brush to remove
dust from the surfaces.
Spots of grease and smudges may be washed away. To clean the
primary mirror, carefully remove the mirror cell from the telescope
by loosening screws, which hold it inside the OTA. Do not remove
mirror from the mirror cell. Carefully wet the mirror surface with a lot
of pure spirit (alcohol) using the cotton cloth. using the same cloth
without pressure clean the mirror surface and then rinse the mirror
under a stream of water. Wait till the water trickles away. Swab
remaining water drops from the surface with a dry cloth edge.
To clean the secondary mirror use the same procedure.
use only quality optical lens cleaning tissue and optical lens
cleaning fluid specifically designed for multi-coated optics to clean
your eyepieces and finderscope.
Lens or mirror surfaces should be cleaned as infrequently as
possible, only when absolutely necessary.
Keep the dust cover on the front of the telescope and the end cap
on the focuser tube when not in use.
