fits the existing accessory mounting holes on the telescope.
Alternatively, the included foam tape can be used.
Operation
The EZ Finder II works by projecting a tiny red dot (it’s not a
laser beam) onto a lens mounted in the front of the unit. When
you look through the EZ Finder II, the red dot will appear to float
in space, helping you locate even the faintest of deep space
objects. The red dot is produced by a light-emitting diode (LED)
near the rear of the sight. A 3-volt lithium battery provides the
power for the diode.
Turn the power knob (see Figure 1) 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. In daylight you may need to cover the front of the
sight with your hand to be able to see the dot, which is purpose-
fully quite dim. 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.
At the end of your observing session, be sure to turn the power
knob counterclockwise until it clicks off. When the white dots on
the EZ Finder II’s body and power knob are lined up, the EZ
Finder II is turned off.
Aligning the EZ Finder II
When the EZ Finder II is properly aligned with the telescope, an
object that is centered on the EZ Finder II’s red dot should also
appear in the center of the field of view of the telescope’s eye-
piece. Alignment of the EZ Finder II is easiest during daylight,
before observing at night. Aim the telescope at a distant object
such as a telephone pole or roof chimney and center it in the
telescope’s eyepiece. The object should be at least 1/4 mile
away. Now, with the EZ Finder II turned on, look though the EZ
Finder II. The object should appear in the field of view.
Without moving the main telescope, use the EZ Finder II’s azi-
muth (left/right) and altitude (up/down) adjustment knobs (see
Figure 1) to position the red dot on the object in the eyepiece.
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, recenter it and adjust the EZ Finder II’s alignment
again. When the object is centered in the eyepiece and on the
EZ Finder’s red dot, the EZ Finder II is properly aligned with the
telescope.
Once aligned, EZ Finder II will usually hold its alignment even
after being removed and remounted. Otherwise, only minimal
realignment will be needed.
Replacing the Battery
Should the battery ever die, replacement 3-volt lithium batteries
are available from many retail outlets. Remove the old battery
by inserting a small flat-head screwdriver into the slot on the
battery casing (Figure 1) and gently prying open the case. Then
carefully pull back on the retaining clip and remove the old bat-
tery. Do not overbend the retaining clip. Then slide the new bat-
tery under the battery lead with the positive (+) end facing down
and replace the battery casing.
