with the Reducer/Corrector Lens
attached, you
should NOT use an eyepiece longer than 35mm focal
length.
CARE AND MAINTENANCE
One added side feature of the Reducer/Corrector Lens
is that it acts as a dust seal for the telescope,
preventing various contaminates from entering the
optical system. If you leave the Reducer/Corrector
Lens on the telescope, be sure to replace the plastic
lens cover on the lens when not in use. This will
minimize dust build-up on the lens itself. If the lens is
removed from the telescope, both plastic covers
should be replaced.
When handling the Reducer/Corrector, be careful not
to touch the lens itself. Failure to do so may result in
smudging the lens.
Special care should be taken when cleaning any
optical instrument so as not to damage the optics. If,
over time, you do experience dust build-up, use a can
of pressurized air to remove it. This is done by
removing the caps from both sides of the diagonal and
spraying the stream of air for approximately 2 to 4
seconds on each side of the lens.
Further cleaning, if necessary, can be done with
cleaning solution and white tissue. You can use
commercially-made camera lens cleaner, or mix your
own. A good cleaning solution is isopropyl alcohol
mixed with distilled water. The solution should be
60% isopropyl alcohol and 40% distilled water.
Apply the cleaner to the tissue and apply to the lens.
Remove residue cleaning solution with a clean tissue.
