Safety Information

• Never look directly at the sun through the telescope or its finder scope. Permanent eye damage, including blindness, can result.
• Do not leave the telescope unsupervised, especially when children are present.
• Handle optical components with care to avoid scratches or damage.
• Keep the telescope away from extreme temperatures and moisture.
• Ensure the tripod is stable on a flat surface to prevent tipping.

Package Contents

Verify that all components listed below are present in your package:

• Telescope Optical Tube

Setup

Follow these steps to assemble your telescope:

1. Attach the Tripod: Unfold the legs of the table tripod. Securely attach the telescope optical tube to the tripod mount using the provided screw. Ensure it is tightened firmly to prevent wobbling.

2. Insert the Zenith Mirror: Slide the chrome barrel of the zenith mirror (diagonal) into the focuser tube at the back of the telescope. Tighten the small thumbscrew on the focuser to hold the diagonal in place. The zenith mirror provides a more comfortable viewing angle, especially for objects high in the sky.
3. Insert an Eyepiece: Choose either the 6 mm or 20 mm eyepiece. Insert the chrome barrel of the chosen eyepiece into the open end of the zenith mirror. Tighten the small thumbscrew on the diagonal to secure the eyepiece. The 20 mm eyepiece provides lower magnification and a wider field of view, useful for locating objects. The 6 mm eyepiece provides higher magnification for detailed views.
4. Attach Smartphone Adapter (Optional): If included, attach the smartphone adapter to an eyepiece. Place your smartphone onto the adapter, aligning its camera lens with the eyepiece. This allows for capturing photos or videos through the telescope.

Operating

Focusing the Telescope

Once an eyepiece is installed, point the telescope towards a distant object (e.g., a tree or building during the day, or the Moon at night). Slowly turn the focus knob located on the side of the focuser tube until the image appears sharp and clear. For astronomical observations, it is recommended to focus on a bright star or the Moon.

Observing Terrestrial Objects

For land observations, the zenith mirror will provide an upright but laterally reversed image. This is normal for astronomical telescopes. Use the 20 mm eyepiece for a wider field of view to locate objects, then switch to the 6 mm eyepiece for more detailed views if desired.

Observing Astronomical Objects

For astronomical observations, the zenith mirror will provide an upright but laterally reversed image. This is standard for refractor telescopes. Begin with the 20 mm eyepiece to locate celestial objects like the Moon or bright planets. Once centered, you can switch to the 6 mm eyepiece for higher magnification and more detailed views. Remember that celestial objects move across the sky, so you will need to periodically adjust the telescope to keep them in view.

Using the Compass

Your telescope may include a small compass integrated into the optical tube. This can be used to help orient yourself and the telescope, particularly when trying to locate objects based on their direction (e.g., North Star, rising sun/moon). Ensure the telescope is level for accurate readings.

Maintenance

• 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 applied to the cloth, not directly to the lens.
• Cleaning the Body: Wipe the telescope body and tripod with a soft, damp cloth. Avoid abrasive cleaners.
• Storage: When not in use, store the telescope in a dry, dust-free environment. Keep the lens caps on to protect the optics. The compact design allows for easy storage in a carrying bag or backpack.
• Avoid Disassembly: Do not attempt to disassemble the optical components of the telescope, as this can void the warranty and damage the instrument.
