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 finished.
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.
CAUTION: DO NOT LOOK DIRECTLY AT THE
SUN. VIEWING THE SUN OR ANY LIGHT
SOURCE WITH THIS OPTICAL DEVICE CAN
CAUSE PERMANENT EYE DAMAGE.

Finderscope
The mount of the finderscope bracket slides into the main body of the
telescope.
Located between the compass and the focus knob.
-
Unscrew the 3 silver thumbscrews located on the finderscope bracket and
place the finderscope through the opening of the finderscope bracket. Tighten
the 3 silver thumbscrews to keep finderscope in place. -
Slide the finderscope bracket into the body of the telescope, located between
the compass and the focus knob. -
Remove cap from the eyepiece of the finderscope.
-
If necessary adjust the thumb screw of finderscope bracket to change the
angle of viewing for the finderscope.
Initial set up is shown in the picture on the left. Should look like picture
on the
right when finished.
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 finished.
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 finished.
WHICH MAGNIFICATION? SELECTING THE CORRECT EYEPIECE
Magnification defines the power of a telescope to enlarge an image or to ‘pull
it
in’ closer for viewing.
Example:
700mrn focal length = 56 x magnification
12.5mm focal length of eyepiece
The required magnification depends upon the object being observed. The
following general guideline is recommended for this purpose: Ideal viewing
conditions are obtained if the magnification is not more than 15x – 20x the
diameter of the objective lens, i.e. an optimal magnification of 100x – 125x
can be
expected with 60 mm diameter objective lens to observe
most celestial objects. A lower magnification power is advisable for the
observation of stars.
The field of view is wider so that the object for observation is more easily
localized. The highest magnification 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 magnification
ratios.
Barlow Lens:
The Barlow lens increases the magnification of the telescope. A 3x Barlow
lens will therefore triple the telescope’s magnification power. Consequently a
56x magnification can be tripled to 168x with a 3x Barlow lens. The highest
magnification 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 fluctuations 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
firmly. This could damage the parts or the internal thread of the holders with
the
result that the screws can no longer be tightened.
