ESSLNB 650130 Reflector Telescope User Manual

1. Introduction

Thank you for choosing the ESSLNB 650130 Reflector Telescope. This manual provides detailed instructions for the assembly, operation, and maintenance of your telescope. Designed for adult astronomers, this instrument offers a large 130mm aperture and high-quality optics for exceptional views of celestial objects. Please read this manual thoroughly before use to ensure optimal performance and a rewarding stargazing experience.

2. Safety Information

• Never look directly at the sun through the telescope or its finder scope without a professionally manufactured solar filter. Permanent and irreversible 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.
• Ensure the tripod is stable on a level surface before attaching the telescope.

4. Setup Instructions

Follow these steps to assemble your ESSLNB 650130 Reflector Telescope:

1. Assemble the Tripod: Extend the legs of the stainless steel tripod to a stable position. Adjust the height as needed using the leg clamps. Attach the accessory tray to the center brace for added stability and storage.
2. Mount the Telescope Tube: Carefully place the telescope tube onto the tripod mount. Secure it firmly using the provided screws or clamps. Ensure the tube is balanced.
3. Attach the Finder Scope: Slide the red-dot finder scope into its bracket on the telescope tube and tighten the retaining screws.
4. Insert Eyepiece: Choose an eyepiece (e.g., K25mm for lower magnification) and insert it into the focuser. If using the Barlow lens, insert the Barlow lens first, then the eyepiece into the Barlow lens.
5. Attach Phone Adapter (Optional): If you plan to use your smartphone for observation or photography, attach the stargazing phone mount to the eyepiece.

5. Operating Instructions

5.1. Initial Alignment and Focusing

1. Finder Scope Alignment: Before observing celestial objects, align the red-dot finder scope with the main telescope. Point the main telescope at a distant, easily identifiable terrestrial object. Look through the finder scope and adjust its alignment screws until the red dot is centered on the same object.
2. Focusing: Look through the eyepiece. Turn the focuser knob slowly until the image is sharp and clear.

5.2. Using Eyepieces and Barlow Lens

Your telescope comes with two K-eyepieces (K10mm and K25mm) and a 2X Barlow lens. The K-eyepieces are designed for clear images with minimal aberrations.

• The K25mm eyepiece provides lower magnification and a wider field of view, ideal for locating objects and observing larger celestial bodies like the Moon or star clusters.
• The K10mm eyepiece offers higher magnification, suitable for detailed views of planets or smaller deep-sky objects.
• The 2X Barlow lens doubles the magnification of any eyepiece it's used with, allowing for a maximum magnification of 130X with the K10mm eyepiece.

5.3. Using the Sky Tonight App

The Sky Tonight app, combined with the adjustable phone holder, simplifies locating celestial objects:

1. Install the App: Download and install the Sky Tonight app on your smartphone.
2. Connect Phone: Secure your smartphone to the telescope's main tube using the phone adapter.
3. Select Object: Open the app and enter the name of the celestial body you wish to observe.
4. Align Telescope: Follow the directional arrows within the app to adjust the telescope's latitude and longitude until it aligns with your desired object. The app will then display detailed information about the object.

5.4. Wireless Remote Control

Use the included wireless remote control to capture steady photos and videos with your smartphone through the telescope, minimizing vibrations.

5.5. Large Aperture Advantage

The 130mm aperture of this reflector telescope provides superior light-gathering power and exceptional resolution, allowing for brighter and clearer images, especially for deep-sky objects.

6. Maintenance

• Cleaning Lenses: Use a soft, lint-free cloth specifically designed for optical lenses. Breathe lightly on the lens to fog it, then gently wipe with the cloth. For stubborn spots, use a small amount of optical cleaning fluid on the cloth, not directly on the lens.
• Cleaning Telescope Body: Wipe the telescope tube and tripod with a soft, damp cloth. Avoid abrasive cleaners.
• Storage: Store the telescope in a dry, dust-free environment. Use dust caps for the main lens and eyepiece openings when not in use.
• Avoid Extreme Temperatures: Do not expose the telescope to extreme hot or cold temperatures, as this can affect its components.
