Product Overview

Familiarize yourself with the main parts of your ESSLNB 70080 Telescope:

Figure 2: Main Components of the Telescope

• Objective Lens: The large lens at the front of the telescope that gathers light.
• Telescope Tube: The main body of the telescope.
• Finderscope: A small telescope mounted parallel to the main telescope, used for locating objects.
• Eyepiece Lens: Interchangeable lenses used to magnify the image.
• Zenith Mirror (Diagonal): Redirects the light path at a 90-degree angle for comfortable viewing.
• Focus Knob: Used to adjust the clarity of the image.
• Control Level: For adjusting the telescope's position.
• Aluminum Tripod: Provides a stable base for the telescope.
• Accessory Tray: Attaches to the tripod for holding eyepieces and other small accessories.
• Tripod Lock: Secures the tripod legs in position.

Setup Instructions

Follow these steps to assemble your telescope:

1. Assemble the Tripod

1. Unfold the aluminum tripod legs.
2. Extend the tripod legs to your desired height (adjustable from 25.2" to 42.1") and secure them using the easy lock mechanisms.
3. Attach the accessory tray to the center brace of the tripod.

2. Mount the Telescope Tube

1. Locate the mounting bracket on the telescope tube.
2. Align the mounting bracket with the altazimuth mount on the tripod head.
3. Secure the telescope tube to the mount using the provided screws or clamps. Ensure it is firmly attached.

3. Attach the Finderscope

1. Slide the finderscope into its bracket on the main telescope tube.
2. Tighten the small screws on the bracket to hold the finderscope in place.

4. Insert the Zenith Mirror and Eyepiece

1. Remove the dust cap from the focuser tube.
2. Insert the zenith mirror (diagonal) into the focuser tube and secure it with the thumbscrew.
3. Insert your chosen eyepiece (e.g., K25mm or K10mm) into the zenith mirror and secure it with the thumbscrew.
4. To increase magnification, you can insert the 3X Barlow lens between the zenith mirror and the eyepiece.

5. Attach the Stargazing Phone Mount

1. Attach the stargazing phone mount to the telescope tube as shown in Figure 4.
2. Place your smartphone securely into the mount.

Operating Instructions

1. Choosing an Eyepiece and Magnification

The telescope comes with two Kellner eyepieces: K25mm and K10mm. The K25mm eyepiece provides 28X magnification, while the K10mm eyepiece provides 70X magnification. For higher magnification, use the 3X Barlow lens:

• K25mm Eyepiece: 28X Magnification
• K10mm Eyepiece: 70X Magnification
• K25mm Eyepiece + 3X Barlow Lens: 84X Magnification
• K10mm Eyepiece + 3X Barlow Lens: 210X Magnification

Start with the lowest magnification (K25mm eyepiece) to locate objects, then switch to higher magnifications for more detailed views.

2. Focusing

Once an object is centered in your eyepiece, slowly turn the focus knob until the image appears sharp and clear. Fine-tune the focus for optimal viewing.

3. Using the Finderscope

The finderscope has a wider field of view than the main telescope, making it easier to locate objects. Look through the finderscope and center the desired object in its crosshairs. Once centered, the object should be visible in the main telescope's eyepiece.

4. Using the Stargazing App

The telescope is compatible with a stargazing app (e.g., Sky Tonight APP) for automatic star tracking. Follow these steps:

1. Download and install the recommended stargazing app using the provided App Install Card or by searching your app store.
2. Launch the app and ensure your smartphone's location services are enabled.
3. The app will generate a list of visible celestial objects based on your exact time and location.
4. Select the celestial body you wish to observe within the app.
5. Follow the app's arrows and instructions to adjust the telescope's latitude and longitude coordinates for precise targeting.
6. The app will help you identify aligned celestial bodies and display detailed information about them.

5. Using the Smartphone Adapter and Wireless Remote

The smartphone adapter allows you to connect your phone to the telescope for real-time observation and photography. The wireless remote control facilitates taking photos without disturbing the telescope's alignment.

1. Attach your smartphone to the stargazing phone mount (as shown in Figure 4).
2. Align your phone's camera with the eyepiece.
3. Use the wireless remote control to trigger your phone's camera shutter, capturing images or videos of your observations.

Maintenance

• Cleaning Lenses: Use a soft, lint-free cloth specifically designed for optical lenses. Gently wipe the objective lens and eyepieces. Avoid touching the optical surfaces with your fingers.
• Dust Protection: Always keep dust caps on the objective lens and eyepieces when not in use.
• Storage: Store the telescope in a dry, dust-free environment. The provided carry case is ideal for protection during storage and transport.
• Avoid Extreme Temperatures: Do not expose the telescope to extreme temperatures or sudden temperature changes, as this can affect the optics.
