Aligning The Ez Finder Ii Reflex Sight - Orion StarMax 90 Instruction Manual

superimposes a dot on the sky, showing exactly
where the telescope is pointed. The EZ Finder II
works by projecting a tiny red dot produced by a
light emitting diode(LED), not a laser beam, onto
a lens mounted in the front of the unit. When you
look through the reflex sight, the red dot will
appear to float in space.
Illustration 6: The EZ Finder II superimposes a
tiny red dot onthe sky, showing right where the
telescope in pointing.
The first time you use the EZ Finder II you may
have to remove the clear plastic tab near the
battery cover; this tab prevents the batteries from
accidentally being drained during storage. 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 Illustration
5.)
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 or near the
field of view of the telescope's eyepiece at lowest
power. Alignment of the sight is easiest during
daylight before observing at night.
1. 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.
2. When the red dot is centered on the distant
object, check to make sure that the object
is still centered in the telescope'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 centered on the red dot of the reflex
sight. (See Illustration 5.)
3. 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
