Configuració
Follow these steps to assemble your Gskyer telescope:
- Set up the Tripod: Extend the legs of the stainless steel tripod to your desired height. Ensure the tripod is stable on a flat surface. Secure the accessory tray to the center brace of the tripod.
- Enganxeu el muntatge: Place the AZ Altazimuth Mount onto the tripod head and secure it using the provided screws.
- Mount the Optical Tube: Attach the telescope optical tube to the AZ mount using the dovetail plate connection. Tighten the locking screws to ensure the tube is firmly in place.
- Install the Finderscope: Slide the 6x30 finderscope into its bracket on the optical tube and tighten the retaining screws.
- Insert the Zenith Mirror: Insert the 48° Erecting BAK7 Prism (diagonal) into the focuser of the telescope. Secure it with the small thumbscrew.
- Attach an Eyepiece: Insert your chosen eyepiece (e.g., 25mm for lower magnification) into the zenith mirror. Secure it with the thumbscrew on the diagonal.
- Attach Phone Adapter (Optional): If using the phone adapter, attach it to the eyepiece and secure your smartphone.

Funcionament del telescopi
1. Aligning the Finderscope
The finderscope helps you locate objects before viewing them through the main telescope. To align it:
- Point the main telescope at a distant, stationary object (e.g., a tree or building) during daylight hours.
- Center the object in the main telescope's eyepiece.
- Look through the finderscope and adjust its alignment screws until the same object is centered in the finderscope's crosshairs.
2. Choosing Eyepieces and Magnification
Your telescope comes with multiple eyepieces and a Barlow lens to achieve different magnifications. Magnification is calculated by dividing the telescope's focal length (600mm) by the eyepiece's focal length.
- 25mm Eyepiece: Provides 24X magnification (600mm / 25mm = 24X). Ideal for wide-field views and locating objects.
- 10mm Eyepiece: Provides 60X magnification (600mm / 10mm = 60X). Good for more detailed views de la Lluna i els planetes.
- 5mm Eyepiece: Provides 120X magnification (600mm / 5mm = 120X). For higher detail on celestial objects.
- 3X Barlow Lens: Trebles the magnification of any eyepiece. For example, a 25mm eyepiece with the 3X Barlow lens provides 72X magnification (24X * 3 = 72X).
Always start with the lowest magnification (25mm eyepiece) to locate your target, then switch to higher magnifications for more detail.

3. Enfocament
Once an object is centered in your eyepiece, slowly turn the focus knob until the image is sharp and clear. Fine-tune the focus for optimal viewing.
4. Terrestre Viewing
The 48° Erecting BAK7 Prism provides an upright image, making the telescope suitable for terrestrial viewing (e.g., bird watching, landscape observation). Without this prism, images would appear inverted.

Manteniment
Proper care will extend the life and performance of your telescope:
- Neteja de lents: Use a soft, lint-free cloth specifically designed for optical lenses. Never use abrasive materials or household cleaners. Gently brush away any dust before wiping.
- Emmagatzematge: Store the telescope in a dry, dust-free environment. Keep lens caps on when not in use to protect the optics.
- Manipulació: Avoid touching optical surfaces with your fingers. Always handle the telescope by its body and mount.
- Canvis de temperatura: Allow the telescope to acclimate to outdoor temperatures before use to prevent condensation on lenses.
Resolució de problemes
Si teniu problemes, consulteu els següents problemes i solucions habituals:
| Problema | Causa possible | Solució |
|---|---|---|
| La imatge està borrosa o desenfocada. | Configuració incorrecta de l'enfocament. | Ajusteu el botó d'enfocament lentament fins que la imatge sigui nítida. |
| No es poden trobar objectes. | Finderscope not aligned; starting with too high magnification. | Align the finderscope (see "Operating" section). Start with the 25mm eyepiece. |
| La imatge està invertida o capgirada. | Erecting prism not used for terrestrial viewing. | Ensure the 48° Erecting BAK7 Prism is inserted for upright images. |
| Image is dim or unclear. | Light pollution; atmospheric conditions; dirty lenses. | Move to a darker location. Wait for clearer skies. Clean lenses carefully. |
| El trípode és inestable. | Cames no completament esteses o bloquejades; superfície irregular. | Ensure all tripod leg locks are secure and the tripod is on a stable, level surface. |
