CARE AND MAINTENANCE

Store the telescope indoors in a dry place. A garage is
ideal; it will keep the optics near the ambient outdoor
temperature so they won't take too long to acclimate.
Keep the dust cover on the front of the telescope and
the cover cap on the focuser when the telescope is not
in use. Otherwise, dust and particles can accumulate on
the optics.
If the telescope is wet from dew, dry the exterior of the
telescope tube and base with a towel before storage.
While a small amount of water on the exterior of the
tube and base won't harm the telescope, storing it wet
long-term could cause corrosion or water damage. The
wooden base has sealed melamine surfaces. Still, water
can seep into cracks if left wet during storage.
It is normal for some dust and particles to accumulate on
the primary mirror over time. They will not have any effect
on optical performance. However, if the primary mirror
gets excessively dirty, you should clean it.
To clean the primary mirror:
1. Remove the primary mirror cell from the telescope
tube by removing the screws on the tube just above
the mirror cell (Figure 25). You'll need the Phillips
head screwdriver to do this.
2. Carefully pull the mirror cell off of the tube.
3. The mirror surface is now exposed for cleaning.
We recommend leaving the primary mirror in its cell
during cleaning.
4. Use a blower bulb and optics cleaning brush to
remove larger particles and dust. In some instances,
this will be all the cleaning necessary.

cleaning, fi rst remove the screws located just above the mirror cell.
