Boitsebiso ba Tšireletseho
- TSOHLE look directly at the sun through the telescope or its finderscope, even for an instant, without a professionally made solar filter that covers the entire front of the telescope. Permanent and irreversible eye damage may result.
- Do not leave the telescope unsupervised, especially when children are present.

Tlhophiso
1. Assemble the Tripod
Unfold the aluminum tripod legs and extend them to your desired height. Secure the legs using the locking clamps. The tripod is adjustable from 16.1 inches (41cm) to 51.6 inches (131cm) for comfortable viewng.
Figure 3: Adjustable aluminum tripod for stable observation.
2. Attach the Telescope Tube
Locate the mounting bracket on the telescope tube. Align it with the tripod head and secure it using the provided screws or quick-release mechanism. Ensure the tube is firmly attached and balanced.
3. Install the Finderscope
Slide the 5x24 finderscope into its mounting bracket on the main telescope tube. Tighten the small screws to hold it in place. The finderscope helps in quickly locating objects before observing them with the main telescope.

4. Insert the Diagonal Prism
Insert the 45° erect diagonal prism into the focuser tube of the telescope. Secure it by tightening the small thumbscrew on the focuser. This prism provides an erect (non-inverted) image, which is ideal for terrestrial viewing and makes celestial observation more intuitive.
Figure 5: The 45° erect-image diagonal prism ensures comfortable and clear observation.
5. Attach the Eyepiece
Insert either the K25mm or K6mm eyepiece into the diagonal prism. Secure it with the thumbscrew. The K25mm eyepiece offers lower magnification and a wider field of view, while the K6mm eyepiece provides higher magnification for more detailed views.
6. Optional: Use the Barlow Lens
For even higher magnification, insert the 3X Barlow lens into the diagonal prism first, then insert your chosen eyepiece into the Barlow lens. This will treble the magnifying power of the eyepiece.
7. Optional: Attach the Phone Adapter
The adjustable phone adapter allows you to capture photos and videos through the telescope. Attach the phone adapter to an eyepiece, then secure your smartphone to the adapter. Adjust the phone's camera to align with the eyepiece for optimal viewing and capture.

Litaelo tsa Ts'ebetso
1. Locating Objects with the Finderscope
Before using the main telescope, use the finderscope to locate your desired object. Look through the finderscope and center the object in its crosshairs. Once centered, the object should be visible in the main telescope's eyepiece.
2. Focusing the Image
Once an object is in view, slowly turn the focus knob on the focuser tube until the image appears sharp and clear. You may need to make minor adjustments as the object moves across the sky.
3. Adjusting Observation Angle
The telescope can be adjusted by 180° in the vertical direction and 360° in the horizontal direction, allowing for flexible observation of various targets.
Figure 7: The telescope offers a wide range of motion for observation.
4. Using the Moon Filter
For observing the moon, screw the metal moon filter onto the bottom of your chosen eyepiece. This filter reduces the brightness of the moon, enhancing contrast and allowing for more comfortable and detailed viewing of lunar features.
Figure 8: The moon filter improves lunar observation by reducing glare.
5. Magnification Calculation
The magnification of your telescope is determined by the focal length of the telescope divided by the focal length of the eyepiece. If using the 3X Barlow lens, multiply the result by 3.
- Bolelele ba Pono ea Telescope: 360mm
- K25mm Eyepiece: 360mm / 25mm = 14.4X
- K6mm Eyepiece: 360mm / 6mm = 60X
- With 3X Barlow Lens:
- K25mm + 3X Barlow: 14.4X * 3 = 43.2X
- K6mm + 3X Barlow: 60X * 3 = 180X
The telescope offers a magnification range of 15X to 180X.

Tlhokomelo
- Lilense tsa ho hloekisa: Use a soft, lint-free cloth specifically designed for optical lenses. Gently wipe the lens surface in a circular motion. For stubborn smudges, use a small amount of optical cleaning fluid on the cloth, not directly on the lens.
- Polokelo: When not in use, store the telescope in a dry, dust-free environment. Keep all lens caps on to protect the optics from dust and scratches.
- Qoba Lithempereichara Tse Feteletseng: Do not expose the telescope to extreme hot or cold temperatures, as this can affect its performance and longevity.
- Litlhahlobo tsa Kamehla: Periodically check all screws and fasteners to ensure they are tight. Do not overtighten.
