Setup Instructions
Unpack and lay out all of the parts in a large, clear area where you will have
room to assemble the pieces.
1. Fully extend the legs of the tripod apart
2. Under the plate of the tripod head is locking screw for the tripod head
3. Place the telescope tube on the mount so that the screw in the mounting
platform lines up with the holes in the telescope
4. Keep telescope in place by tightening the mounting plate adjustment
Initial set up is shown in the picture on the left. Should look like picture on the
right when nished.
5. Remove caps from telescope
Note: When mounting the parts ensure that the securing screws are not tightened
too tightly. Tightening too tightly could result in damage the parts or the internal
thread of the holders.

Attaching the Accessories
Accessory Tray
1. Included with the telescope is an accessory tray that is mounted in the center
and on the leg braces. If necessary fully extend the legs of the tripod apart.
Initial set up is shown in the picture on the left. Should look like picture on the
right when nished.
Eyepiece
1. Select an eyepiece, place it into the rotating diagonal. Lock the eyepiece it into
place with the thumb screw.
Barlow Lens
The included 3x Barlow lens triples the magnifying power of each eyepiece.
See Barlow Lens page 7
Eyepiece initial set up is shown in the picture on the left. Should look like picture
on the right when nished.
Finderscope
The mount of the nderscope bracket slides into the main body of the telescope.
Located between the compass and the focus knob.
1. Unscrew the 3 silver thumbscrews located on the nderscope bracket and
place the nderscope through the opening of the nderscope bracket. Tighten
the 3 silver thumbscrews to keep nderscope in place.
2. Slide the nderscope bracket into the body of the telescope, located between
the compass and the focus knob.
3. Remove cap from the eyepiece of the nderscope.
4. If necessary adjust the thumb screw of nderscope bracket to change the
angle of viewing for the nderscope.
Initial set up is shown in the picture on the left. Should look like picture on the
right when nished.

How to Use Telescope:
First try out your telescope in the daytime and learn to use the telescope looking
at easily identiable objects. Get familiar with the telescope’s movements,
pointing, focusing, different eyepieces, and magnifying powers. Below is some
information on how to use the telescope.
Telescope Movement:
In order to move the telescope
horizontally (left to right)
- Loosen Horizontal Axis Screw
In order to move the telescope vertically
(up and down)
- Turn the Tripod Handle to the left to
loosen the tripod vertically allowing
movement.
Adjusting the Finder Scope:
Since the telescope has a limited eld of view, it can be quite difcult to locate
a given star or planet. For this reason the telescope is tted with a nder scope
with reticule for orientation. It is advisable to complete the following settings in
daylight.
1. Insert the eyepiece with the lowest magnication in the Zenith mirror
or Zenith prism. Look at a stationary easily recognizable object that
is not further away than 300m. Turn the telescope with the horizontal
axle, and move the vertical axle until the object is in the middle of the
eld of view, and then focus the image. Tighten the adjusting screw
on the mount so that the telescope remains in this position (the higher
the object is above the horizon, the easier it is to locate).
2. Now look through the nder scope. If the object seen through the
telescope is not visible, then release the adjusting screws and move
the nder scope until the object can be seen. Now retighten the
adjusting screw while ensuring that the object remains visible in the
centre or the nder scope. To simplify this procedure use the
adjusting screws to adjust the object in the centre. The nder scope
will move in the direction of the screw in which it is being turned.
All screws can be nally tightened as soon as the setting with the
eyepiece coincides with that of the nder scope.
WHICH MAGNIFICATION? SELECTING THE CORRECT EYEPIECE
Magnication denes the power of a telescope to enlarge an image or to ‘pull it
in’ closer for viewing.
Example:
700mrn focal length = 56 x magnication
12.5mm focal length of eyepiece
The required magnication depends upon the object being observed. The
following general guideline is recommended for this purpose: Ideal viewing
conditions are obtained if the magnication is not more than 15x - 20x the
diameter of the objective lens, i.e. an optimal magnication of 100x - 125x can be
expected with 60 mm diameter objective lens to observe most celestial objects. A
lower magnication power is advisable for the observation of stars.
The eld of view is wider so that the object for observation is more easily
localized. The highest magnication power should only be used for particularly
clear observations of the moon an object that is relatively close and exceptionally
bright, so that good detail resolution is achieved at high magnication ratios.
Barlow Lens:
The Barlow lens increases the magnication of the telescope. A 3x Barlow
lens will therefore triple the telescope’s magnication power. Consequently a
56x magnication can be tripled to 168x with a 3x Barlow lens. The highest
magnication power of the Barlow lens should only be used for large and bright
objects such as the moon and the brightest planets, as well as for nights with
optimal observation conditions.
To use the Barlow lens take the angle prism out of the tube. Insert the Barlow
lens into the rotating diagonal and then attach the required eyepiece to the
Barlow lens, focusing is then completed in the customary manner.
VERY IMPORTANT GENERAL REMARKS
CAUTION
TO AVOID EYE DAMAGE NEVER LOOK THROUGH THE TELESCOPE INTO
ANOTHER OPTICAL INSTRUMENT, INTO THE SUN OR A LIGHT SOURCE.
NEVER LEAVE THE TELESCOPE UNATTENDED, A CHILD COULD LOOK AT
THE SUN WITH IT AND SUFFER PERMANENT EYE DAMAGE.
Avoid sudden temperature uctuations as the moisture in the air will condense on
the objective lens. Should this happen, then place the objective lens not too close
to a source of heat and allow the moisture to evaporate slowly.
When mounting the parts ensure that the securing screws are not tightened too
rmly. This could damage the parts or the internal thread of the holders with the
result that the screws can no longer be tightened.
