With proper care, your telescope should rarely need any maintenance work. To maintain your telescope in the best
possible condition, observe the follow suggestions:
1. When your telescope isn’t in use, replace all lens covers to keep dust and contaminants off the optical surfaces.
2. A small amount of dust on any optical surface isn’t a problem and doesn’t need to be removed. If the dust builds
up, then use a can of compressed air and a camels hair brush to remove the dust. To remove fingerprints or other
contaminants, use an optical cleaning kit or the Celestron Lens Pen (#93575).
3. If the inside of the objective lens needs cleaning, it should be done by a professional. Either have your instrument
serviced by a telescope repair facility or return it to the factory for servicing.

Collimation or alignment of the optical system is done at the factory before shipment.
1. If your telescope has received very rough handling during transport or is dropped, it may need collimation.
Refer to the following sketch to check if your telescope is in
collimation. If you look into the eyepiece adapter (without an
eyepiece) at the top of the focuser, this is what you should
see. If the reflection of your eye is off center, then
collimation is necessary.
2. Adjustments to the collimation of the telescope can be made
by turning the collimation adjustment screws (d) located at
the rear of the optical tube.
3. If your telescope is out of collimation, the best way to re-
collimate it is with a good collimation tool. Celestron offers a
Newtonian Collimation Tool (#94183) with detailed
instructions that make it an easy chore.
