The following magnification levels can be achieved when using the standard eyepiece in conjunction with the 3x
Barlow lens:
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.
