up or 180 degrees opposite in the down position, your
choice.
Also notice the altitude axis tensioning knob near the top of
the mount arm (refer to Figure 1). It is used to set the desired
tension for rotation of the telescope by hand in altitude. Turn
the knob clockwise to increase the tension; turn it counter-
clockwise to decrease the tension. There is no tensioning knob
for azimuth rotation
Inserting the Star Diagonal (Mak-Cass and Refractor)
and Eyepiece
A star diagonal is used with the Maksutov-Cassegrain and
refractor models to divert the light at a right angle from the light
path of the telescope. This allows you to observe in positions
that are more comfortable than if you were to look straight
through the telescope. A diagonal is not used with Newtonian
reflectors; none is included with the StarSeeker reflector mod-
els.
To attach the star diagonal:
1.
Remove the protective dust cap from the 1.25" accessory
adapter or focuser.
2.
Loosen the two thumbscrews on the 1.25" adapter or
focuser and slide the chrome portion of the star diagonal
into it (see Figure 8). Then retighten the thumbscrews to
hold the star diagonal in place.
The eyepiece is the optical element that magnifies the image
focused by the telescope. The eyepiece fits directly into the
1.25" focuser (on reflector models) or star diagonal. To install
one of the included eyepieces:
1.
Loosen the two thumbscrews on the focuser's 1.25"
accessory collar or the star diagonal, then slide the
chrome barrel of the eyepiece into it (Figure 9).
2.
Tighten the thumbscrews to hold the eyepiece in place.
Installing the EZ Finder II
Before installing the EZ Finder II on the telescope, you will
need to insert the included CR2032 3V lithium button cell bat-
tery in the EZ Finder II. If there is a small plastic tab sticking
out from the battery compartment cover, you must remove it
for the battery to make contact with the EZ Finder's electronic
circuitry. The tab can then be discarded.
Turn the EZ Finder II upside down as shown in Figure
1.
10A .
2.
Insert a small, flat-blade screwdriver into the notch in the
battery compartment cover and gently pry it off.
3.
Slide the battery under the retaining clip with the positive
(+) side facing up (touching the clip) (10B).
4.
Then press the battery compartment cover back on.
Should the battery die, replacement CR2032 batteries
are available at many stores where small batteries are
sold or online.
5.
To attach the dovetail mounting bracket to the EZ Finder
II, loosen the two thumbscrews on the bottom rail of the
EZ Finder II. Slide the EZ Finder II onto the bracket and
tighten the two thumbscrews (See Figure 11). Then

simply slide the mounting bracket's foot into the dovetail
mounting shoe as shown in Figure 12 and tighten the
thumbscrew on the shoe to secure the mounting bracket.

The EZ Finder II should be oriented so that the sight tube
is facing the front of the telescope, as shown. Tighten the
thumbscrew on the dovetail shoe to secure the EZ Finder
II in place.
