The EZ Finder II superimposes a tiny red dot on the
sky, showing right where the telescope is pointed.
The first time you use the EZ Finder II you will need to
remove the clear plastic tab near the battery cover; this tab
prevents the batteries from accidentally being drained dur-
ing shipment. Turn the power knob clockwise until you hear
the "click" indicating that power has been turned on. Look
through the back of the reflex sight with both eyes open to
see the red dot. Position your eye at a comfortable distance
from the back of the sight. The intensity of the dot is adjusted
by turning the power knob. For best results when stargazing,
use the dimmest possible setting that allows you to see the
dot without difficulty. Typically a dimmer setting is used under
dark skies and a bright setting is used under light-polluted
skies or daylight. (See Figure 4.)
Aligning the EZ Finder II Reflex Sight
When the EZ Finder II is properly aligned with the telescope,
an object that is centered on reflex sight's red dot should also
appear in the center of the field of view of the telescope's eye-
piece. Alignment of the sight is easiest during daylight, before
observing at night.
1. Aim the telescope at a distant object such as a telephone
pole or roof chimney and center it in the telescope's eye-
piece. The object should be at least 1/4 mile away. Now,
with the EZ Finder II turned on, look though it. The object
will appear in the field of view near the red dot.

2. Without moving the main telescope, use the EZ Finder
II's azimuth (left/right) and altitude (up/down) adjustment
knobs to center the red dot on the object in the eyepiece.
3. When the red dot is centered on the distant object, check
to make sure that the object is still centered in the tele-
scope's field of view. If not, re-center it and adjust the EZ
Finder II's alignment again. When the object is centered
in the eyepiece and on the reflex sight's red dot, the EZ
Finder II is properly aligned with the telescope and is
ready to be used.
The EZ Finder II alignment should be checked before every
observing session. Choose any distant target (during the day)
or bright star (at night), center the object in the telescope's
eyepiece, and then adjust the knobs until the object is cen-
tered on the red dot of the reflex sight. (See Figure 5.)
At the end of your observing session, be sure to turn the
power knob counterclockwise until it clicks off. When the two
white dots on the EZ Finder II's body and power knob are
lined up, the EZ Finder II is turned off.
Replacing the Battery
Replacement 3-volt lithium (CR-2032) batteries are available
from many retail outlets. Remove the old battery by inserting
a small flat-head screwdriver into the slot on the battery cover
and gently prying open the cover. Then carefully pull back
