Configuració

The Celestron Travel Scope 70 is designed for quick and easy assembly without the need for any tools. Follow these steps to set up your telescope:

  1. Desempaquetar components: Carefully remove all components from the backpack and packaging.
  2. Set Up Tripod: Extend the tripod legs to your desired height and ensure they are stable on a flat surface. The tripod features adjustable legs for various viewposant posicions.
  3. Attach Telescope Tube: Securely attach the telescope optical tube to the tripod mount using the provided screw. Ensure it is firmly tightened.
  4. Install Finderscope: Slide the finderscope into its bracket on the telescope tube and tighten the small screws to hold it in place. The finderscope helps in locating objects before viewing them through the main eyepiece.
  5. Insert Erect Image Diagonal: Insert the 45° erect image diagonal into the focuser tube of the telescope. This accessory ensures that images are viewed upright and correctly oriented, which is especially useful for terrestrial observations.
  6. Attach Eyepiece: Insert either the 20mm or 10mm eyepiece into the diagonal. The 20mm eyepiece provides a wider field of view for general observation, while the 10mm eyepiece offers higher magnification for more detailed views.

Funcionament del telescopi

Once your telescope is set up, you can begin observing. Here are key operational aspects:

  • Enfocament: Use the focus knob located on the side of the telescope tube to bring objects into sharp focus. Turn it slowly until the image is clear.
  • Canvi d'ampliació: Swap between the 20mm and 10mm eyepieces to change the magnification. The 20mm eyepiece provides 20x magnification, while the 10mm eyepiece provides 40x magnification. For higher magnification, you can use an optional Barlow lens (not included in all models) which doubles the power of any eyepiece.
  • Erect Image Diagonal: The included 45° erect image diagonal ensures that your views are correctly oriented, making it suitable for both astronomical and terrestrial viewing.
  • Using the Finderscope: The 5x24 finderscope provides a wide field of view to help you locate objects quickly. Align the finderscope with the main telescope during the day on a distant object, then use it to pinpoint celestial targets at night.
  • Smartphone Adapter (DX models): Some models include a smartphone adapter that allows you to attach your phone to the eyepiece for easy viewing and astrophotography. This is particularly useful for sharing your observations or capturing images.
  • Bluetooth Remote (DX models): For stable astrophotography, a Bluetooth remote shutter release is included with DX models. This allows you to trigger your phone's camera without touching the telescope, minimizing vibrations.
  • Moon Filter (DX models): A moon filter can be screwed onto the eyepiece to reduce the brightness of the Moon, enhancing contrast and making lunar features more comfortable to observe.

Manteniment

To ensure the longevity and optimal performance of your Celestron Travel Scope 70, proper maintenance is essential:

  • Òptiques de neteja: Use a soft, lint-free cloth specifically designed for optical lenses to clean the telescope's lenses. Avoid touching the optical surfaces with your fingers. For stubborn smudges, use a small amount of optical cleaning fluid.
  • Protecció contra la pols: Always keep the lens caps on when the telescope is not in use to prevent dust accumulation. Store the telescope in its backpack in a dry, dust-free environment.
  • Atenció general: Avoid exposing the telescope to extreme temperatures or sudden temperature changes. Handle all components with care to prevent accidental damage.

Specific maintenance instructions beyond general care are not detailed in the provided product information. Please refer to the full user manual for comprehensive guidance.

Resolució de problemes

Here are some common issues you might encounter with your Celestron Travel Scope 70 and potential solutions:

  • Unstable Image/Wobbly Tripod: The included lightweight tripod may exhibit some wobble, especially when fully extended or during adjustments.
    • Solució: Ensure the tripod legs are fully extended and locked. For increased stability, consider placing weights on the tripod legs or using a sturdier camera tripod if available. Using the Bluetooth remote shutter release (for DX models) can also minimize vibrations when taking photos.
  • Dificultat per concentrar-se: If images appear blurry, the focus may need adjustment.
    • Solució: Slowly turn the focus knob until the image becomes sharp. Ensure the eyepiece is fully inserted into the diagonal.
  • Image Appears Upside Down or Reversed: This is common with some telescopes, but the Travel Scope 70 includes an erect image diagonal.
    • Solució: Ensure the 45° erect image diagonal is correctly inserted. If using without the diagonal, astronomical views may appear inverted.
  • Barlow Lens Internals Loose (reported in some reviews): In rare cases, the internal components of the Barlow lens might shift during shipping.
    • Solució: Carefully inspect the Barlow lens. If components are loose, gently re-seat them or contact customer support for assistance.
