4. Налада і зборка
Follow these steps to assemble your Gskyer EQ901000 telescope.
- Усталюйце штатыў: Spread the tripod legs to a stable position. Attach the accessory tray to the center brace of the tripod.
- Прымацуйце экватарыяльную мацаванне: Secure the equatorial mount head to the top of the tripod. Ensure it is firmly tightened.
- Усталюйце вал процівагі і процівагу: Thread the counterweight shaft into the mount. Slide the counterweight onto the shaft and secure it with the locking screw.
- Падключыце аптычную трубку: Place the telescope optical tube into the mounting rings on the equatorial mount. Tighten the rings securely, ensuring the tube is balanced.
- Усталюйце відашукальнік: 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. Кіраванне тэлескопам
Once assembled, follow these steps for observation.
5.1 Aligning the Finderscope
The finderscope must be aligned with the main telescope for easy object location.
- Point the main telescope at a distant, stationary object (e.g., a tree or building) during daylight hours.
- Цэнтруйце аб'ект у акуляры галоўнага тэлескопа.
- 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, палягчаючы пошук аб'ектаў.
- 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 Факусоўка
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. Тэхнічнае абслугоўванне і догляд
Proper care will ensure the longevity and performance of your telescope.
- Чыстка оптыкі: 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.
- захоўванне: Store the telescope in a dry, dust-free environment. Use the dust caps for the objective lens and focuser when not in use.
- Агульны догляд: Avoid exposing the telescope to extreme temperatures or sudden temperature changes. Keep it away from moisture. Periodically check all screws and knobs for tightness.

7. Выпраўленне непаладак
Вось рашэнні распаўсюджаных праблем, з якімі вы можаце сутыкнуцца:
| праблема | Магчымая прычына | Рашэнне |
|---|---|---|
| Выява размытая або не ў фокусе. | Фокусер адрэгуляваны няправільна. | Slowly turn the focuser knob until the image is sharp. Ensure the eyepiece is fully inserted. |
| Cannot find objects with the main telescope. | Шукальнік не сумяшчальны з асноўным тэлескопам. | 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. |
| Выява выглядае цьмянай або цёмнай. | 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. |
| Тэлескоп моцна трасецца. | 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. |
