BEFORE YOU BEGIN
This instruction manual is applicable to all the models listed on the cover. Follow the
instructions for your specific model in the manual. Flip the booklet over to the
reverse side if your telescope comes with a SynScan AZ GoTo hand control, instead
of a simple tracking SynTrek hand control. Read the entire instructions carefully
before beginning. Your telescope should be assembled during daylight hours.
Choose a large, open area to work to allow room for all parts to be unpacked.

NEVER LOOK AT THE SUN WITH THE NAKED EYE OR WITH A
TELESCOPE (UNLESS YOU HAVE THE PROPER SOLAR FILTER).
PERMANENT AND IRREVERSIBLE EYE DAMAGE MAY RESULT.
IF OBSERVING THE SUN (WHILE USING A PROPER SOLAR FILTER)
WITH YOUR TELESCOPE, MAKE SURE THAT THE FINDERSCOPE HAS A
DUST CAP OVER THE OBJECTIVE END OR REMOVE THE
FINDERSCOPE.
NEVER USE YOUR TELESCOPE TO PROJECT AN IMAGE OF THE SUN
ONTO ANY SURFACE. INTERNAL HEAT BUILD-UP CAN DAMAGE THE
TELESCOPE AND ANY ACCESSORIES ATTACHED TO IT.
NEVER USE AN EYEPIECE SOLAR FILTER OR A HERSCHEL WEDGE.
INTERNAL HEAT BUILD-UP INSIDE THE TELESCOPE CAN CAUSE
THESE DEVICES TO CRACK OR BREAK, ALLOWING UNFILTERED
SUNLIGHT TO PASS THROUGH TO THE EYE.
DO NOT LEAVE THE TELESCOPE UNSUPERVISED, EITHER WHEN
CHILDREN ARE PRESENT OR ADULTS WHO MAY NOT BE FAMILIAR
WITH THE CORRECT OPERATING PROCEDURES OF YOUR TELESCOPE.

TRIPOD SET UP
1. Remove the tripod from the box and spread the
legs apart until fully extended.
2. Adjust the desired height of the tripod before
attaching the fork arm and your optical tube.
Minor adjustments can be made later. Loosen the
locking mechanisms on each leg and slide the
legs to the desired height and then retighten them.
MOUNT SET UP
1. Next you will attach your Multi-function mount to
the tripod. Locate the 3/8" threaded bolt in the top
of the tripod platform. Then, find the mating 3/8"
threaded hole underneath the Fork Arm Base.
Thread the 3/8" bolt of the tripod platform into the
3/8" threaded hole in the fork arm base until it is
good and tight (Fig.6).
2. Locate the 1/4x20 Mounting Platform. Slide it down
the slot on the Fork Arm as in dicated in Fig.7.
Secure by tightening the thumb screws.
TELESCOPE ASSEMBLY
ATTACHING THE TELESCOPE TUBE TO THE MOUNT
1. If you are using the telescope for tracking astronomical objects,
attach the optical tube to the Mounting Platform so that the Fork
Arm is located on the right hand side (Fig.8). If the telescope is
installed incorrectly you will not be able to use the latitude scale
on the top of the Fork Arm. Thread the 1/4x20 Mounting Screw
into the 1/4x20 tripod adapter of the optical tube and make sure it
is tight. Do not overtighten the screw.
Telescopes with a dovetail bar attached can be installed
directly onto the Multi-function mount without using the
Mounting Platform.
ATTACHING A CAMERA TO THE MOUNT
1. For general terrestrial use, the camera can be secured on
the Mounting Platform any way you wish. Thread the 1/4x20
Mounting Screw into the camera and make sure it is tight. Do
not overtighten the screw.

Do NOT overtighten the 1/4x20 Mounting Screw or it may
cause damage to the screw.

You must be careful not to use an optical tube that is too
heavy or too big as the motor assembly will not be able to
operate properly and you may damage the mount.

U sing the Red Dot Finder
Fig.a
The Red Dot Finder is a zero magnification pointing tool that uses
a coated glass window to superimpose the image of a small red
dot onto the night sky. The Red Dot Finder is equipped with a
variable brightness control, azimuth adjustment control, and
altitude adjustment control (Fig.a). The Red Dot Finder is
powered by a 3-volt lithium battery located underneath at the
front. To use the Finder, simply look through the sight tube and
move your telescope until the red dot merges with the object.
Make sure to keep both eyes open when sighting.

Aligning the Red Dot Finder
Like all finderscopes, the Red Dot Finder must be properly
aligned with the main telescope before use. This is a simple
process using the azimuth and altitude control knobs.
Fig.b
1. Open the battery cover by pulling it down (you can gently pry at
the 2 small slots) and remove the plastic shipping cover over
the battery (Fig.b).
2. Turn on the Red Dot Finder by rotating the variable brightness
control clockwise until you hear a "click". Continue rotating the
control knob to increase the brightness level.
Insert a low power eyepiece into the telescope's focuser.
3. Locate a bright object and position the telescope so that the
object is in the centre of the field of view.
With both eyes open, look through the sight tube at the object.
4. If the red dot overlaps the object, your Red Dot Finder is
perfectly aligned. If not, turn its azimuth and altitude adjustment
controls until the red dot is merged with the object.

Fig.c
F ocusing
Slowly turn the focus knobs (Fig.c), one way or the other, until the
image in the eyepiece is sharp. The image usually has to be finely
refocused over time, due to small variations caused by
temperature changes, flexures, etc. This often happens with short
focal ratio telescopes, particularly when they haven't yet reached
outside temperature. Refocusing is almost always necessary
when you change an eyepiece or add or remove a Barlow lens.
C alculating the magnification (power)
The magnification produced by a telescope is determined by the focal length of the eyepiece that is used with it.
To determine a magnification for your telescope, divide its focal length by the focal length of the eyepieces you
are going to use. For example, a 10mm focal length eyepiece will give 80X magnification with an 800mm focal
length telescope.
magnification =
800mm
Focal length of the telescope
Focal length of the eyepiece
=
10mm
= 80X
When you are looking at astronomical objects, you are looking through a column of air that reaches to the edge of
space and that column seldom stays still. Similarly, when viewing over land you are often looking through heat
waves radiating from the ground, house, buildings, etc. Your telescope may be able to give very high magnification
but what you end up magnifying is all the turbulence between the telescope and the subject. A good rule of thumb
is that the usable magnification of a telescope is about 2X per mm of aperture under good conditions.

1. You will find a latitude scale with two index pointers near
the top of the fork arm. If you are using a camera or a
telescope mounted on the Mounting Platform, use the
pointer on top as reference. If your telescope is mounted
directly on a dovetail bar, use the lower point as reference.
2. Manually adjust the telescope tube until the latitude scale
reads 0 (Fig.h).
3. Next, the telescope must be pointing North from the
location you are using.

Setting the local latitude for accurate tracking
Setting the local latitude is not required to track an astronomical object but it greatly
enhances the tracking accuracy. It requires that you know the latitude of the
observing site. To set the latitude for the Northern Hemisphere, use the directional
buttons to adjust the telescope tube until the latitude scale reads 0. Turn off the
power and turn it back on again. Now use the hand control to move the telescope
tube until the latitude scale reads your local latitude. Press the "Fast" and "Slow"
buttons simultaneously to store the local latitude into the system (Fig.i).

Setting the local latitude only needs to be done once. The information will be stored
in the hand control even when the power is turned off.
Use the same
or
key to end adjusting scale reading to 0 degree and setting your local
latitude. This will help eliminate the influence of mechanical backlash. For example, if
key is
the last key that you used to set the scale to 0 degree, you should also use
key as the last
key for setting the scale reading to your local latitude.
Hand Control Operation

CRUISE
To activate the TRACKING FUNCTION, you must first find the astronomical
object you are seeking. The preferred method of finding objects is called
"star-hopping" and there is much written on this method. Remember, you must
used the Hand Control unit to move the telescope as you cannot move it
manually. When you are ready to track (when the object is in the center of the
field of view), press the "Guide" and "Slow" buttons in combination and tracking
will be activated (Fig.l). When you want to cancel "tracking" and slew in higher
speed, press the same button combination. Note that when tracking is
activated, one of the "Guide", "Slow" or "Fast" buttons will flash.

Setting up the telescope
Fig.m
The telescope does not require setup for terrestrial use. The telescope can
start from any position. However, if the telescope is positioned in one spot and
the Cruise function is utilized, setting a Reference Point to start and end a
viewing session will save a lot of time for you --- you will not need to reset the 6
Cruising positions before every viewing session. The Reference Point is
defined as the point to which the optical tube is pointing when the power switch
is turned on. (See below for information on the Cruise function.)

If you want to permanently erase a set position, return the mount to
the Reference Position. Turn the power off and then turn it back on
again. Hold down the "SET" button and press the numeric key
corresponding to the position you want to erase. This is to override the
previous stored information with 0. In the CRUISE and SCAN modes,
the mount will recognize this and bypass this position and go to the
next position instead.
The mount allows a total of 6 stored positions. If there is a vacant
one available, it is recommended that you store the Reference
