accessory installation
Now that the base is assembled and the optical tube assem-
bled and mounted, all that remains is to attach the EZ Finder
II reflex sight and pop an eyepiece into the focuser.
EZ Finder ii
Using the included dovetail mounting bracket, the EZ Finder II
will slip neatly into the dovetail base pre-installed on the upper
tube section adjacent to the focuser. Just slide the dovetail
mounting bracket into the telescope’s dovetail mounting base
and tighten the thumbscrew on the base to secure the mount-
ing bracket. Make sure the sight tube of the EZ Finder II is
forward (closest to front opening of telescope).
operating the EZ Finder ii
Before installing the EZ Finder II on the telescope, you’ll need
to insert the included 3-volt lithium battery.
1. Insert a small, flat-blade screwdriver into the notch in the
battery casing and gently pry it off (
Figure 26).
2. Slide the CR2032 3V lithium battery under the retaining
clip with the positive (+) side facing down (touching the
clip).
3. Then press the battery casing back on.
Should the battery die, replacement CR2032 batteries are
available at many stores where small batteries are sold.
The EZ Finder II works by projecting a tiny red dot (it is 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 to pinpoint your target
object
(Figure 25). The red dot is produced by a light-emitting
diode (LED) near the rear of the sight. Turn the power knob
(see Figure 26) 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 purposefully
quite dim. The intensity of the dot is adjusted by turning the
power knob. For best results when stargazing, use the dim-
mest possible setting that allows you to see the dot without
difficulty. Typically a dimmer setting is used under dark skies
and a brighter setting is needed under light-polluted skies or
in daylight.
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
eyepiece. Alignment of the EZ Finder II is easiest during day-
light, 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 it.
The object should appear in the field of view. Without moving
the main telescope, use the EZ Finder II’s azimuth (left/right)
and altitude (up/down) adjustment knobs (see
Figure 26)
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, re-center 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, the EZ Finder II will usually
hold its alignment even after being removed and remounted.
Otherwise, only minimal realignment will be needed. At the
end of your observing session, be sure to turn the power knob
to the Off position.
using Eyepieces
The final step in the assembly process is to insert an eye-
piece into the telescope’s focuser. First, take the cover cap
off the focuser drawtube. To use the 2" DeepView eyepiece,
loosen the two thumbscrews on the 2" accessory collar (on
the end of the focuser drawtube) and remove the 1.25" adapt-
er. Then place the 2" eyepiece directly into the 2" accessory
collar and secure it with the two thumbscrews loosened previ-
ously
(Figure 27). If you cannot achieve focus, you may need
to install the included 2" extension adapter on the focuser,
then insert the eyepiece into it. The other eyepiece and 1.25"
