HELPFUL HINTS FOR SETTING UP YOUR TELESCOPE
- Unpack the tripod from the box. Next, spread the tripod legs (7) so that the leg braces are fully extended and rest safely at the base of the tripod center post. Fasten all locks to hold legs securely in place.
- Slide the telescope bracket (5) and adjust the holes.
- Take out the finderscope (14) from the box, remove the two knurled thumb screws from the telescope tube (4), position the finderscope on the telescope tube so that the holes in the base of the bracket line up with the exposed holes in the telescope tube, replace the two knurled thumb screws and fasten securely.
- Remove the lens caps (11 & 1) from the eyepiece and the objective lens (10 & 2).
OBSERVING ASTRONOMICAL OBJECTS THROUGH YOUR TELESCOPE
- Glance through the main telescope’s eyepiece (10) 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 bolt (6) to keep the accuracy of your telescope steady.
- Now adjust the focusing tube (9) by turning the focusing knob (12) slowly back and forth until the blurred object becomes precise.
- If you are going to be looking through the telescope for a short period of time, you can insert the eyepiece (10) directly into the focusing tube (9). To be more comfortable when using your telescope for longer periods of time, place the diagonal mirror (13) into the focusing tube (9) and the eyepiece (10) into the diagonal mirror
COMPONENTS OF THE SMARTPHONE ADAPTOR
- ADJUSTABLE ARM
- SMARTPHONE HOLDER
- RACKET
- QUICK RELEASE LEVER
- ARC

SETTING UP AND REMOVING THE SMART PHONE ADAPTER
Conventional methods which help identify and locate the celestial objects often trouble the novice users either by cost or manual labor. A new, convenient and accurate way is to utilize the smartphone software application. To aid in using the software application, you have a smartphone adapter to secure your smartphone onto the telescope. Thus, your smartphone and telescope can be moved and adjusted together to locate the celestial objects with your desired angle and direction. To place your smart phone on the adaptor and remove it after use, follow these directions
Attach the smartphone to the holder
- Loosen the large knob at the back of the adaptor and put the smartphone on it with face up.
- Adjust the position of the horizontal arm to fit the width of the smartphone and tighten the large knob so that the smartphone is securely held in place
Attach the telescope clip to the telescope tube
- Loosen the small knob on the base of the clip
- Open the arc of the ring
- Attach clip to the telescope tube with the flat side in upper position
- Close the ring, secure by tightening the small knob.
Attach the smartphone to and remove it from the telescope
- Slide the smartphone adapter to the telescope clip.
- Press the quick release lever and slide the smartphone adaptor out
USING STAR WALKTM 2
A stargazing smartphone software application (e.g. Star Walk ™ 2 for iOS and Android) helps you find and identify the celestial objects easily.
Select “Take a Tour” (Menu Take a tour) to familiarize yourself with the various app features. The App language will follow your smartphone’s language setting
Features Highlight
IDENTIFY THE CELESTIAL OBJECTS
After the smartphone adapter is attached to the telescope, the smartphone orientation is aligned with the telescope. Utilizing the smartphone’s location, orientation and time information, a star map application can show the real time simulated sky view on the screen matching the view through the telescope. Names of the stars or celestial objects are shown on screen. The information of the screen is automatically updated when users adjust the telescope or move the telescope to a different location.
SEARCH AND DIRECT
Another advantage of using the application software is that users can search for a celestial object. The screen will guide users which direction to move the telescope
INFORMATION OF THE CELESTIAL OBJECTS
Users can select the objects on the screen to read detailed information like their internal structures, orbits and compositions
TIME MACHINE
Besides the real-time star map, users can extend the control of star viewing into the past and future. Users can see how specific celestial events unfold through the change of time
Besides using smartphone adapter, a finderscope is also provided to help locating celestial objects
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
To align the finderscope follow these simple directions: (Note: We strongly recommend that you follow these directions during daylight hours)
- 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 centered in the field of view and focus.
- 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 centered as much as possible.
- 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 in focus. – If it moved, then readjust your telescope and repeat the alignment step for the finderscope
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 25X, you are seeing it as if you are 25 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 (e.g., 4mm, 10mm, 20mm etc.)
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
CARE OF YOUR TELESCOPE
Your telescope should be kept away from dust and moisture. If the lenses get dirty, blow any dust particles off before cleaning. Clean the lenses with a moistened lens tissue. Always store your telescope in the box when not in use.
DO NOT VIEW SUN THROUGH TELESCOPE AS SERIOUS INJURY TO EYE MAY RESULT.
