3. Product Parts Introduction

Familiarize yourself with the main parts of your telescope:

• Main Tube: The primary optical component housing the objective lens.
• Finderscope: A small telescope with a wide field of view, used for locating objects before viewing them through the main telescope.
• Focus Adjustment Wheel: Used to bring objects into sharp focus.
• Eyepiece: Interchangeable lenses that determine the magnification.
• Zenith Mirror: An accessory that allows for more comfortable viewing angles, especially for objects high in the sky.
• Angle Adjustment: Mechanisms to adjust the telescope's vertical and horizontal position.
• Tripod: Provides a stable base for the telescope.
• Tripod Lock Buckle: Secures the tripod legs at the desired height.

4. Setup Instructions

4.1. Tripod Assembly

1. Unfold the tripod legs and extend them to your desired height.
2. Secure the legs using the tripod lock buckles. The tripod is adjustable from 20.08 inches (51 cm) to 55.12 inches (140 cm).
3. Ensure the tripod is stable on a flat surface.

4.2. Attaching the Main Tube and Accessories

1. Mount the main telescope tube onto the tripod head and secure it firmly.
2. Insert the Zenith Mirror into the eyepiece holder at the end of the main tube.
3. Choose an eyepiece (e.g., 25mm for lowest magnification) and insert it into the Zenith Mirror.
4. Attach the finderscope to its designated bracket on the main tube.

4.3. Attaching the Phone Mount

1. Attach the stargazing phone mount to the eyepiece.
2. Secure your smartphone into the phone clip on the mount. This allows for capturing images or using stargazing apps.

5. Operating the Telescope

5.1. Magnification and Eyepieces

The telescope comes with three eyepieces (4mm, 10mm, 25mm) and a 5X Barlow lens, offering a wide range of magnifications. Magnification is calculated by dividing the telescope's focal length (600mm) by the eyepiece's focal length. The Barlow lens multiplies the magnification of any eyepiece by 5X.

5.2. Finding and Focusing Objects

1. Start with the lowest magnification: Always begin with the 25mm eyepiece for a wider field of view, making it easier to locate objects.
2. Use the finderscope: Look through the finderscope and align its crosshairs with the object you wish to observe.
3. Center the object: Once the object is centered in the finderscope, it should be visible in the main telescope's eyepiece.
4. Adjust focus: Use the focus adjustment wheel to bring the image into sharp focus.
5. Increase magnification (optional): Once the object is in focus with the 25mm eyepiece, you can switch to a higher magnification eyepiece (10mm or 4mm) or add the 5X Barlow lens for more detailed views.

5.3. Day and Night Use

This telescope is designed for dual-purpose use. It can be used for observing celestial bodies at night and for viewing terrestrial scenery during the day. For daytime viewing, a small magnification eyepiece is often sufficient to obtain clear, wide-field images.

5.4. Using Moonlight Filters

The telescope includes three moonlight filters (Green, Red, Blue) that are compatible with 1.25" eyepieces. Simply screw the desired filter onto the threaded end of your eyepiece before inserting it into the Zenith Mirror. These filters can enhance contrast and reduce glare when observing bright objects like the Moon, revealing more surface details.

5.5. Stargazing with a Phone Mount

The included phone mount allows you to attach your smartphone to the eyepiece. You can download stargazing applications to help identify celestial objects or use your phone's camera to capture images and videos through the telescope.

6. Maintenance

6.1. Cleaning the Lenses

• Use a soft, lint-free cloth specifically designed for optical lenses.
• For stubborn smudges, use a small amount of optical lens cleaning fluid applied to the cloth, not directly to the lens.
• Avoid touching the lens surfaces with your fingers.
• Do not use abrasive materials or household cleaners.

6.2. Storage

• When not in use, store the telescope in its carrying bag in a dry, dust-free environment.
• Keep dust caps on all lenses and eyepieces.
• Avoid storing the telescope in areas with extreme temperature fluctuations or high humidity.

7. Troubleshooting

• Image is blurry: Adjust the focus wheel slowly until the image is sharp. Ensure the correct eyepiece is fully inserted.
• Cannot find objects: Start with the lowest magnification eyepiece (25mm). Use the finderscope to locate and center the object before looking through the main telescope.
• Image is dim: Ensure the objective lens is clean. Observe from a dark location away from light pollution. The 90mm large aperture and fully multi-coated lenses are designed to improve light transmittance and reduce light refraction, providing brighter images.
• Image is upside down or reversed: This is normal for astronomical telescopes without an erecting prism. The Zenith Mirror provides a corrected image for vertical orientation but may still be horizontally reversed. For terrestrial viewing, an erecting eyepiece (not included) would provide a fully corrected image.

8. Specifications

9. User Tips

• Start Simple: For beginners, the Moon is an excellent first target. Its large size and bright features make it easy to find and focus on.
• Dark Adaptation: Allow your eyes to adjust to the darkness for at least 15-20 minutes before observing to maximize your night vision.
• Stability is Key: Always ensure your tripod is set up on a firm, level surface to minimize vibrations, especially at higher magnifications.
• Dress Warm: Stargazing often involves long periods outdoors at night, so dress appropriately for the weather.
• Use Stargazing Apps: Leverage the phone mount with a stargazing app to quickly identify constellations, planets, and deep-sky objects.
