Product Components
Your telescope package includes the following items:
- Telescope Optical Tube
- Adjustable Aluminum Tripod
- Finderscope (5x24)
- Eyepieces (20mm and 9mm)
- Diagonal Mirror
- Moon Filter (13% transmission)

Setup Instructions
- Unpack Components: Carefully remove all items from the backpack and packaging.
- Set up the Tripod: Extend the tripod legs to the desired height. The tripod is adjustable from 17.7 inches to 52 inches. Ensure the tripod is stable on a flat surface. The tripod head features a bubble level and a compass for proper alignment.
- Attach the Telescope Tube: Secure the telescope optical tube to the tripod head platform using the provided mounting screws. Tighten securely.
- Install the Finderscope: Attach the 5x24 finderscope to its designated bracket on the main telescope tube. Align the finderscope with the main telescope during daylight hours by focusing on a distant, stationary object.
- Insert the Diagonal Mirror: Place the diagonal mirror into the focuser tube of the telescope. Secure it with the small thumbscrew.
- Insert an Eyepiece: Choose either the 20mm or 9mm eyepiece and insert it into the diagonal mirror. Secure it with the thumbscrew on the diagonal.

Operating Instructions
1. Adjusting Magnification
The telescope comes with two eyepieces for different magnifications:
- 20mm Eyepiece: Provides 30X magnification. Ideal for wider field views and locating objects.
- 9mm Eyepiece: Provides 66X magnification. Suitable for more detailed observations of the Moon and planets.
To change magnification, simply swap the eyepieces in the diagonal mirror. Ensure the thumbscrew is tightened to secure the eyepiece.
2. Focusing the Telescope
Once an object is centered in your view, slowly turn the large focus knob located on the focuser tube until the image appears sharp and clear. Fine adjustments may be needed as objects move across the sky or as atmospheric conditions change.
3. Using the Moon Filter
The included moon filter transmits only 13% of incoming light, which is essential for comfortable and detailed observation of the Moon. To use, gently screw the moon filter onto the bottom of your chosen eyepiece before inserting the eyepiece into the diagonal.
4. Using the Smartphone Adapter
The smartphone adapter allows you to capture photos and videos through the telescope. Attach your smartphone to the adapter, ensuring the phone's camera lens is perfectly aligned with the eyepiece. Secure the adapter to the eyepiece and then insert the eyepiece into the diagonal. Use your phone's camera app to view and record.

Maintenance
Proper maintenance ensures the longevity and performance of your telescope:
- Cleaning Lenses: Use a soft, lint-free cloth specifically designed for optical lenses. Avoid touching the lens surfaces with your fingers. For stubborn smudges, use a specialized optical cleaning solution sparingly.
- Storage: Store the telescope and all accessories in the provided backpack in a dry, dust-free environment. Avoid extreme temperatures and humidity.
- Handling: Always handle the telescope with care. Avoid sudden movements or impacts that could misalign optical components.
Troubleshooting
If you encounter issues with your telescope, refer to the following common problems and solutions:
- Blurry Image: Adjust the focus knob slowly. Ensure the correct eyepiece is securely inserted. Check for condensation on the lenses.
- Difficulty Locating Objects: Ensure the finderscope is properly aligned with the main telescope. Start with the lowest magnification eyepiece (20mm) to locate objects, then switch to higher magnification (9mm) for detailed viewing.
- Unstable View: Ensure the tripod legs are fully extended and locked, and the telescope is securely mounted. Avoid using the telescope on uneven or shaky surfaces.
