2. Safety Information

• Never look directly at the Sun through the telescope or its finder scope without a professionally manufactured solar filter. Doing so can cause immediate and irreversible eye damage, including blindness.
• Do not leave the telescope unsupervised, especially when children are present.
• Handle optical components with care to avoid scratches or damage.
• Ensure the tripod is stable on a flat surface before use to prevent tipping.

3. Package Contents

Verify that all components are present in your package:

• Telescope Optical Tube Assembly (OTA)

4. Assembly and Setup

1. Set up the Tripod:

   Unfold the aluminum tripod legs and extend them to your desired height. The tripod is adjustable from approximately 40cm to 104cm (15.7 to 40.9 inches). Ensure the legs are fully spread for maximum stability. You can attach a heavy object to the hook at the bottom of the central column for added stability.

2. Attach the Telescope Tube:

   Locate the mounting plate on the tripod head. Align the telescope tube with the mounting screw on the tripod head and securely fasten it. Ensure it is tight to prevent movement.
3. Install the Diagonal Prism:

   Insert the 45° diagonal prism into the focuser tube of the telescope. Secure it with the small thumbscrew on the focuser. The diagonal prism corrects the image orientation, making observations more comfortable.

4. Insert an Eyepiece:

   Choose either the K6mm or K25mm eyepiece. Insert it into the diagonal prism and secure it with the thumbscrew. Start with the K25mm eyepiece for a wider field of view and easier object location.

5. Attach and Align the Finder Scope:

   Mount the finder scope onto its bracket on the main telescope tube. Secure it with the provided screws. To align the finder scope, point the main telescope at a distant, stationary object (e.g., a treetop or building) during daylight hours. Look through the main telescope's eyepiece and center the object. Then, look through the finder scope and adjust its alignment screws until the same object is centered in the finder scope's crosshairs.

5. Operating Instructions

5.1 Finding Objects

• Use the finder scope to locate your desired celestial object. The finder scope provides a wider, lower-magnification view, making it easier to sweep the sky and pinpoint targets.
• Once the object is centered in the finder scope's crosshairs, it should be visible in the main telescope's eyepiece.

5.2 Focusing

• Turn the focus knob located on the focuser tube until the image appears sharp and clear. Fine adjustments may be needed as objects move or as your eyes adjust.

5.3 Changing Magnification

• To change magnification, remove the currently installed eyepiece and insert a different one. The K25mm eyepiece provides 16X magnification, ideal for wide-field views and locating objects. The K6mm eyepiece provides 76X magnification, suitable for more detailed observations of the Moon and planets.

5.4 Adjusting the Telescope Position

• The telescope mount allows for both horizontal (360°) and vertical (180°) movement. Use the horizontal motion lock and vertical adjustment handle to smoothly track objects across the sky.

6. Maintenance

• Cleaning Lenses: Use a soft, lint-free cloth specifically designed for optical lenses. Gently wipe the lens surfaces. For stubborn smudges, use a small amount of optical cleaning fluid applied to the cloth, not directly to the lens. Avoid touching the lens surfaces with your fingers.
• Storage: When not in use, store the telescope in its shockproof backpack in a cool, dry place to protect it from dust and moisture. Keep eyepieces in their protective containers.
• General Care: Avoid exposing the telescope to extreme temperatures or sudden temperature changes. Do not overtighten screws or knobs, as this can cause damage.
