PORTABLE REFLECTOR TELESCOPE

Z130 TUBE ORIENTATION
The Z130 has a dovetail rail and adjustable tube rings to
allow the eyepiece to be positioned at the most comfortable
viewing angle. To rotate the tube, loosen the tube ring clamp
screws on the tube rings slightly, then rotate the optical tube
so the eyepiece is positioned around a 45º angle from the
ground. Make sure the optical tube is forward enough in
the tube rings so that you can point the telescope straight
overhead without bumping into the base.
Z130 TUBE DISASSEMBLY
You can quickly remove the optical tube from the base
for easy storage and transport. Simply loosen the black
thumbscrew from the dovetail holder on the base and slide
the optical tube off the rail.
USING 1.25” EYEPIECES
1.
The 1.25” is the most commonly used eyepiece format.
The measurement of 1.25 inches is the diameter of the
eyepiece barrel.
2.
The eyepiece holder and focuser come already
attached to the optical tube, next to where the
finderscope is mounted.
3.
Remove the plastic dust cover from the eyepiece holder.
4.
Loosen the silver thumbscrew on the focuser drawtube.
5.
Take out your 1.25” eyepiece. Remove the plastic covers.
6.
Slide the chrome end of the eyepiece into the
eyepiece holder.
7.
Tighten the bottom thumbscrew to hold eyepiece
in place.
8.
View through the eyepiece and focus as needed. (See
focusing section.)
9.
To remove the eyepiece, loosen the silver thumbscrew.
10.
To remove, loosen the thumbscrew and pull the
eyepiece out of the focuser.
11.
Use the plastic dust covers to protect the eyepiece
and focuser during storage.
TELESCOPE BASICS
ALTITUDE AND AZIMUTH
1.
Your Zhumell portable reflector is adjustable along two
axes - altitude (up/down) and azimuth (left/right). You
can adjust the telescope’s position along one or both
axes at the same time.
2.
Gently take hold of the end of the optical tube and
move it either left or right (it will spin about its central
azimuth bolt) or up and down.
3.
The telescope can be positioned to view anywhere in
the night sky, but be sure to let it move naturally; never
force your telescope to move.
4.
To tighten the altitude motion, simply tighten the
large altitude tension knob located on the base. You
can adjust the tension so that the telescope holds its
position but still easily moves by hand.
FOCUSING THE IMAGE
1.
Insert the 1.25” eyepiece into the focuser.
2.
Find a bright star and center it in the eyepiece. When
the image is out of focus, the star looks like a doughnut.
If focusing during the day, find an easily recognizable
object like a sign or streetlight.
3.
Turn the focus knobs until the star focuses to a
point of light. Bright stars will sometimes show a
plus-shaped flare (called diffraction spikes) coming
from the secondary mirror support at the front of
the telescope.
4.
Changing eyepieces typically requires readjusting
the focus.
