8. TELESCOPE MAINTENANCE

With proper care your telescope should rarely need any maintenance work.

A. When not in use, always replace all lens covers to keep dust and contaminants off the optical surfaces.

B. A small amount of dust on any optical surface is ok. If the dust builds up then use a can of compressed

air and then a camel's hair brush to remove the dust.

C. If the mirrors need cleaning, they should be cleaned by a professional. Either have your instrument

serviced by a telescope repair facility or return it to the factory.

D. Collimation or alignment of the optical system is done at the factory before shipment. There is no

adjustment you can make and if the instrument is dropped or very roughly handled, it will have to

returned to the factory for proper alignment.
