- Equatorial Mount: Advanced EQ mount for precise tracking of celestial objects.
2. Безбедносне информације
Please read and understand these safety guidelines before using your telescope.
- Никада не гледајте директно у сунце through the telescope or its finderscope without a professionally manufactured solar filter. Permanent eye damage or blindness can result.
- Do not leave the telescope unsupervised, especially when children are present.
- Пажљиво рукујте оптичким компонентама како бисте избегли огреботине или оштећења.
- Ensure the tripod is stable on a level surface to prevent tipping.

4. Подешавање и монтажа
Follow these steps to assemble your Gskyer EQ901000 telescope.
- Поставите статив: Spread the tripod legs to a stable position. Attach the accessory tray to the center brace of the tripod.
- Attach the Equatorial Mount: Secure the equatorial mount head to the top of the tripod. Ensure it is firmly tightened.
- Install the Counterweight Shaft and Counterweight: Thread the counterweight shaft into the mount. Slide the counterweight onto the shaft and secure it with the locking screw.
- Причврстите оптичку цев: Place the telescope optical tube into the mounting rings on the equatorial mount. Tighten the rings securely, ensuring the tube is balanced.
- Инсталирајте Финдерскоп: Slide the 6x30 finderscope into its bracket on the optical tube. Tighten the small screws to hold it in place. Ensure the finderscope is oriented correctly, not backwards.
- Insert the Diagonal and Eyepiece: Insert the 48° erecting prism (diagonal) into the focuser. Then, insert one of the eyepieces (e.g., K25mm) into the diagonal and secure it with the thumbscrew.

5. Руковање телескопом
Once assembled, follow these steps for observation.
5.1 Поравнање тражила
The finderscope must be aligned with the main telescope for easy object location.
- Усмерите главни телескоп ка удаљеном, непокретном објекту (нпр. дрвету или згради) током дана.
- Центрирајте објекат у окулару главног телескопа.
- Look through the finderscope and use its adjustment screws to center the same object in the finderscope's crosshairs.
5.2 Using Eyepieces and Barlow Lens
The telescope comes with multiple eyepieces and a Barlow lens to vary magnification.
- Start with the lowest magnification eyepiece (K25mm) for a wider field of view, што олакшава лоцирање објеката.
- Once an object is centered, you can switch to higher magnification eyepieces (K10mm, 5mm) for more detailed views.
- The 3X Barlow lens triples the magnification of any eyepiece it is used with. Insert the Barlow lens into the diagonal first, then insert the eyepiece into the Barlow lens.

5.3 Фокусирање
To achieve a clear image, rotate the focuser knob until the image appears sharp. Fine adjustments may be needed as objects move or as your eye adjusts.

5.4 Using the Equatorial Mount
The equatorial mount allows you to track celestial objects as they move across the night sky due to Earth's rotation. After aligning the mount with the celestial pole (Polaris in the Northern Hemisphere), you can use the slow-motion controls to smoothly follow objects with minimal effort.
6. Одржавање и њега
Proper care will ensure the longevity and performance of your telescope.
- Чишћење оптике: Use a soft, lint-free cloth specifically designed for optical lenses. Gently wipe the lens surfaces. For stubborn smudges, use a small amount of optical cleaning fluid on the cloth, not directly on the lens. Avoid touching optical surfaces with your fingers.
- Складиштење: Store the telescope in a dry, dust-free environment. Use the dust caps for the objective lens and focuser when not in use.
- Општа нега: Avoid exposing the telescope to extreme temperatures or sudden temperature changes. Keep it away from moisture. Periodically check all screws and knobs for tightness.

КСНУМКС. Решавање проблема
Ево решења за уобичајене проблеме на које можете наићи:
| Проблем | Могући узрок | Решење |
|---|---|---|
| Слика је мутна или ван фокуса. | Фокусер није правилно подешен. | Slowly turn the focuser knob until the image is sharp. Ensure the eyepiece is fully inserted. |
| Cannot find objects with the main telescope. | Финдерскоп није поравнат са главним телескопом. | Align the finderscope during daylight hours as described in Section 5.1. Start with the lowest power eyepiece (K25mm) for a wider field of view. |
| Image appears dim or dark. | High magnification eyepiece used in poor viewing conditions; dirty optics. | Switch to a lower magnification eyepiece. Clean the objective lens and eyepieces if necessary (refer to Section 6). Allow telescope to acclimate to outdoor temperature. |
| Finderscope image is backwards or inverted. | Finderscope installed incorrectly. | Ensure the finderscope is inserted into its bracket with the wider end (objective lens) facing forward, towards the front of the main telescope tube. |
| Telescope shakes excessively. | Tripod not stable; loose connections. | Ensure tripod legs are fully extended and locked. Tighten all screws and knobs on the mount and optical tube. Observe from a stable surface. |
