2. Attach the Optical Tube:

   Mount the telescope optical tube onto the altazimuth mount of the tripod. Secure it firmly using the provided screws or clamps. Ensure the tube is balanced.
3. Install the Finder Scope:

   Slide the finder scope into its bracket on the main telescope tube and tighten the retaining screws. The finder scope helps in locating objects before viewing them through the main telescope.

4. Insert the Eyepiece:

   Loosen the thumbscrew on the focuser. Insert the desired eyepiece (K20mm for lower magnification, K9mm for higher magnification) into the focuser and tighten the thumbscrew to secure it.

5. Attach the Mobile Phone Adapter (Optional):

   If you wish to use your smartphone for photography, attach the mobile phone adapter to the eyepiece. The adapter is designed to fit both K20mm and K9mm eyepieces. Secure your smartphone in the adapter.

Operating Instructions

1. Aligning the Finder Scope

Before observing, the finder scope must be aligned with the main telescope. This is best done during daylight hours.

1. Point the main telescope at a distant, easily identifiable object (e.g., a treetop, a street sign).
2. Center the object in the main telescope's eyepiece.
3. Look through the finder scope and adjust its alignment screws until the same object is centered in the finder scope's crosshairs.

2. Focusing

Once an object is located, turn the focuser knob slowly until the image is sharp and clear. Fine-tune the focus as needed, especially when changing eyepieces.

3. Observing Celestial Objects

• Start with the K20mm eyepiece (lower magnification) to locate and center objects.
• Once centered, you can switch to the K9mm eyepiece for higher magnification and more detailed views.
• Use the rough adjustment and positioning gimbal to smoothly track celestial objects as they move across the sky.

4. Terrestrial Viewing

The telescope can also be used for terrestrial viewing (e.g., bird watching, landscape observation). For upright images, a diagonal prism is typically used. Ensure your setup provides a correctly oriented image for terrestrial use.

Maintenance and Care

• Cleaning Optics: 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 on the cloth, not directly on the lens.
• Storage: When not in use, store the telescope and its accessories in the provided carrying backpack in a dry, dust-free environment. Keep dust caps on the optical tube and eyepieces.
• Handling: Avoid touching optical surfaces with bare hands. Always hold the telescope by its non-optical components.
• Environmental Protection: Do not expose the telescope to extreme temperatures or sudden temperature changes, which can cause condensation.
