scope. This allows you to observe in positions that are more
comfortable than if you were to look straight through the tele-
scope. A diagonal is not used with Newtonian reflectors; none is
included with the StarSeeker reflector models.
To attach the star diagonal:
1. Remove the protective dust cap from the 1.25" accessory
adapter. (2" adapter on the 150mm)
2. Loosen the two thumbscrews on the adapter and slide the
chrome portion of the star diagonal into it (see Figure 7).
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 8).
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 battery in

the EZ Finder II.

1. First open the battery compartment cover by lightly
pressing the lock tab forward while lifting the tab (Figure
9a). Remove the cover.
2. Place the CR2032 battery – positive (+) side up – under
the metal retaining clip in the battery compartment
(Figure 9b).
3. Then replace the cover and snap it closed.
4. Should the battery ever die, a replacement CR2032
battery is available from many retail outlets.
5. Then simply slide the mounting bracket's foot into the
dovetail mounting shoe as shown in Figure 10 and
tighten the thumbscrew on the shoe to secure the
mounting bracket.
6. The EZ Finder II should be oriented so that the sight tube
is facing the front of the telescope, as shown in Figure
10. Tighten the thumbscrew on the dovetail shoe to
secure the EZ Finder II in place.

The EZ Finder II
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
11). The red dot is produced by a light-emitting diode (LED)
