set screw to hold the eyepiece securely in place.

11) A 3X Barlow lens is supplied to triple the basic magnifying power provided by an
eyepiece. In viewing situations where very high magnifying powers are desired, insert
the 3X Barlow lens between the eyepiece and the focusing tube (See Fig. 10).

FINDER SCOPE ALIGNMENT
Since a telescope has a narrow field of view by design, it can be challenging to locate a
particular star or planet. For this reason the telescope is fitted with a low-power, wide-
field miniature telescope called a finder scope. Always use your finder scope to locate
the object you want to view FIRST.
The finder scope should be aligned with the
main telescope tube
before you begin using the telescope,
in order that both
scopes are positioned to always provide exactly the same angle and view.
Note: Objects in the finder scope are upside down. This is normal and is common to all
astronomical telescopes.
