forth until the blurred object becomes precise.
HOW MUCH POWER: CHOOSING THE EYE LENS
Power refers to the ability of a telescope to enlarge an image, or, in effect, bring it
closer to the viewer. Amount of magnifying power is signified by a number
followed by an X (read "power"). So if you view an object at 60X, you are
seeing it as if you are 60 times closer to that object.

Power is calculated by dividing the focal length of your telescope's objective lens
(probably indicated on the focus tube) by the focal length of the eye lens you
select. The focal length of the eye lens is usually indicated on the eyepiece itself.
The longer the focal length of the eyepiece, the less the magnifying power of the
telescope; the shorter the focal length, the greater the power. So when you
select an eye lens to insert into the diagonal prism, you're really choosing what
magnifying power you wish to use for observation.
Using the digital camera module as a PC camera:
1. Screw the objective lens unit back to the digital eyepiece module if it has
been removed for telescope viewing. Care should be taken not to make
fingerprints or dust on the lens and the sensor of the camera.
2. Place the camera unit on the stand as shown below.
Figure 6
3. Connect the camera module to the USB port of the computer
- 9 -
4. Start “PhotoImpression” or other Imaging applications from the Windows
Start menu.
5. Adjust the focus by rotating the lens until a clear image is displayed.
6. You can take still pictures and save them in the computer using the same
procedure as described in the section “Using the Telescope in Digital Mode”.
7. To use the camera module as a web camera for video conference, you need
to install applications like “Netmeeting” or “MSN Messenger”, which can be
downloaded from Microsoft’s web site. Please refer to the corresponding
application manual.
Handling note:
The image sensor inside the digital eyepiece is a delicate integrated circuit and
must be handled carefully. When you remove the lens from the camera, dust may
fall on the sensor. Only use a blower to clean the dust. Never touch the sensor.

Components Of The Telescope
Read the following information and instructions before use. Follow them and
keep them for reference.
- 1 -
How to Care For Your Telescope
Appropriate care of the telescope will allow many years of pleasant viewing enjoyment.
The Objective Lens
The objective lens of Telescope has been intensely polished and established to minute tolerances. It must
be cleaned with care and as seldom as possible to avoid affecting its precision and performance. An
inexperienced person must never take the lenses out of their mount.
Cleaning The Lens
Clean the lens only when it is required. The first step is to remove the dust with a camelhair brush or an
ear-type syringe. Set few drops of ether or isopropyl alcohol on a piece of clean cotton that has been
washed several times and wipe the lenses very delicately, avoiding circular motion. In addition, blow any
remaining lint or dust off with an ear-type syringe.
Sudden Temperature Changes
If possible, avoid taking the telescope from cold outside air into a warm room. This will make the objective
lens to be covered with condensed moisture, which must be removed at once. To do this, place the
objective lens at a safe distance from heat source and let it warm slowly until the moisture has vanished.
It is important to note that any stains left on the lenses must be
delicately wiped off after the lenses are completely dry.

• Unpack the tripod legs (21) from the box.
• To fix tripod legs to Mount (22), align holes of tripod legs with those of the Mount. (Figure 2a)
• Then secure each leg by placing a long 2’’ bolt with washer into the hole given and fixed with a
wingnut and washer.
• Now tighten the bolts.
Note : When fixing tripod legs to Mount, be sure that hinged flange on each tripod leg faces inward. The
tripod Accessory Tray (19) will attach to these flanges.
STEP 2
• Stand the tripod up vertically and spread the tripod legs fully apart.
• Loosen the 3 leg screws.
• Grab Mount and lift.
• Then drag out the extension of the tripod legs to the desired height (at equal lengths) and tighten the
thumb screw in each leg to maintain it in position.

• Insert Diagonal Mirror (4) into the Focusing Tube (3).
• Now insert Eyepiece (6) into Diagonal Mirror.
STEP 7
• Place the telescope tube assembly and the Yoke onto the tripod mount and tighten from the
underside with the small locking knob provided. (Figure 2c) Insert a brass stud into the screw hole
before tightening the Azimuth Locking Knob(18). (Figure 3d)
STEP 8
• An Erecting Eyepiece has been provided for terrestrial viewing. It is provided to erect the upside
down image seen through an astronomical telescope.
• When using the Erecting Eyepiece, remove the Diagonal Mirror and insert the Erecting Eyepiece (18)
into the Focusing Tube (Figure 4).
STEP 9
• For use of Barlow, insert the Barlow Lens into the Focusing Tube.
• Insert the Diagonal Mirror into the Barlow.
• Now the Eyepiece can then be inserted into the Diagonal Mirror (Figure 5).
Observing Astronomical Objects Through Your Telescope
1. Glance through the main telescope’s Eyepiece (6) for your object. (Note : You may have to alter the
angle of the telescope slightly.) The object will most likely seem to be blurry at this stage, but that is
normal. You are just trying to get the object in the viewing field of your telescope lens. Once you have
accomplished this task, fasten the knob to keep the accuracy of your telescope steady.
2. Now adjust the Focusing Tube (3) by turning the Focusing Ring (2) slowing back and forth until the
blurred object becomes precise. You can also use the Fine Focus Adjustment Control (5) for more
precise adjustment.
3. If you are going to be looking through the telescope for a short period of time, you can insert the
Eyepiece directly into the Focusing Tube. To be more comfortable when using your telescope for
longer periods of time, place the Diagonal Mirror (4) into the Focusing Tube and the Eyepiece into the
Diagonal Mirror.
Viewing Terrestrial Objects Through Your Telescope
For viewing of terrestrial objects, remove the Diagonal Mirror (4) and the Eyepiece (6) from the Focusing
Tube (3) and insert the Erecting Eyepiece (25). The Erecting Eyepiece (25) can also be used as a 21X
Microscope by placing the objective end (the end with the transparent tube) flat on an object and looking
through the Eyepiece.

How To Use the Telescope
Our telescope offers an extensive selection parts and accessories for your telescope to further enhance
the exploration of worlds beyond. As well, it is a precision optical instrument certain to give many years of
enjoyment and entertainment.
Viewing
What you see through a telescope and how accurate you see it is a function of three factors ;
• Power / Magnification
• Brightness
• Resolution / Clarity of image
It is a common misunderstanding that the more power you have, the better it is. Indeed, essential functions
of a telescope are to magnify the image, or give the effect of being closer to object of observation.
However, there are limits to how much power to use effectively. With every increase in magnification,
there is a corresponding reduction of brightness and resolution. Too much magnification and the image
will become dim and blurry so that the features of the object become vague. For best view of any
astronomical body, you mist strike a balance between the three viewing qualities.
Furthermore, with every increase in power, there is a decrease in field of view. The field of view is the
circle of sky you see as you look through your telescope. The more you increase magnification, the more
close that circle becomes. You will also notice that celestial bodies seem to move fast across the field of
view even at low powers. That movement is still more recognizable at high powers. High power will
provide some dramatic views of lunar or planetary features, but can also be somewhat frustrating until you
acquire a certain level of expertise at tracking objects smoothly.
Aligning the Finderscope
The relatively high magnifying power of the telescope results in a limited field of view. Therefore, finding a
particular star or planet desired to observe could be a little hard.
To aid in correctly aiming your telescope, you have a finderscope. Your finderscope is a small , low power
telescope equipped with crosshairs, and it provides an incomparably wider field of view than your main
telescope. When the finderscope is correctly aligned, locating a celestial body via the main telescope
becomes less difficult.
By loosing the Finderscope Position Adjustment Control (7), you can adjust the Finderscope to your
desired position.
To align the finderscope follow these simple directions:
(Note : We strongly recommend that you follow these directions during daylight hours).
1. Install the lowest power eye lens into the diagonal mirror.
- Pick out an easily recognized, stationary object no closer than a thousand yards away.
- Rotate your telescope along its horizontal axis and raise the telescope along vertical axis until
the object is centred in the field of view and focus.
Note: Tighten the Locking Screw on the mount to hold the telescope in position. The higher the object
above the horizon, the less difficult the position of the telescope.
2. Look via the finderscope
- If the object lined up in the telescope is not observable, unfasten the adjustment screws and
move the finderscope around until visible.
- Once in focus, tighten the adjustment screws while keeping the object centred as much as
possble. - 5 -
Important Note : The finderscope function is for viewing of the sky only, therefore, the object will always
be upside down.
3. Use the adjustment screws to zero in on the object.
- Loosen the adjustment screws on one side, then tighten adjustment screws on the other side to
move the object squarely onto the crosshairs.
- Recheck telescope to make sure that it is still on focus.
- If it moved, then readjust your telescope and repeat the alignment step for the finderscope.
Power Strength : Selecting The Eye Lens
Power means the ability of telescope to increase an image, or appear to bring the image closer to the
viewer. Value of magnifying power is distinguished by a number followed by an X (read power). Therefore,
If you view an object at 175X, you are seeing it as though you are 175 times closer to that object.
Power is calculated by dividing the focal length of objective lens of your telescope by the focal length of the
eye lens you choose. The focal length of the eye lens is usually indicated on the eyepiece itself. For
example : 4mm
700 mm (focal length of objective lens)
Example: -------------------------------------------------------------------- = 175 X (power)
4 mm (focal length of eyepiece)
The longer the focal length of the eyepiece, the less the magnifying power of the telescope. Whereas the
shorter the focal length, the greater the power. Therefore, when choosing an eye lens to insert the
diagonal prism, you are actually selecting what magnifying power you wish to use for inspection.
