3. Assembly
Assembling the telescope for the first time should take about
30 minutes.You will need a Phillips head screwdriver and a
flat head screwdriver.All screws should be tightened securely
to eliminate flexing and wobbling, but be careful not to over-
tighten or the threads may strip.Refer to Figure 1 during the
assembly process.
During assembly (and anytime, for that matter), DO NOT
touch the surfaces of the telescope mirrors or the lenses of
the finder scope or eyepieces with your fingers.The optical
surfaces have delicate coatings on them that can easily be
damaged if touched inappropriately.NEVER remove any lens
assembly from its housing for any reason, or the product war-
ranty and return policy will be voided.

legs, one at a time, to the base of the mount by sliding a
