2. Інфармацыя па бяспецы
- Never look directly at the Sun through the telescope or its finder scope without a professionally manufactured solar filter. Гэта можа прывесці да пастаяннага і незваротнага пашкоджання вачэй, у тым ліку да слепаты.
- Заўсёды сачыце за дзецьмі падчас выкарыстання тэлескопа.
- Асцярожна звяртайцеся з аптычнымі кампанентамі, каб пазбегнуць драпін або пашкоджанняў.
- Ensure the telescope is securely mounted on a stable tripod or mount to prevent accidental falls.
- Avoid exposing the telescope to extreme temperatures or sudden temperature changes.

4. Ідэнтыфікацыя кампанентаў
Азнаёмцеся з асноўнымі часткамі вашага тэлескопа:
- Аб'ектыў: The large lens at the front of the telescope, composed of a triplet ED APO design with HOYA FCD100 glass for superior chromatic aberration correction.
- Dew Shield: Extends from the front of the telescope to protect the objective lens from dew formation and stray light.
- Carbon Fiber Optical Tube: The main body of the telescope, constructed from lightweight and thermally stable carbon fiber.
- Cradle Rings and Handle: Used to secure the optical tube to a mount and provide a convenient carrying handle.
- Vixen-Style Dovetail Plate: Attached to the cradle rings, this plate allows the telescope to be mounted onto compatible equatorial or alt-azimuth mounts.
- 2.5-inch HEX Focuser: A robust focusing mechanism designed for precise adjustments and capable of supporting heavy accessories.
- Finder Scope Base: A mounting point for an optional finder scope, which aids in locating celestial objects.
- Дыяганаль: An optical accessory that redirects the light path at a 90-degree angle, providing a more comfortable viewпазіцыя.

5. Настройка
Follow these steps to set up your telescope for observation:
- Мантаж тэлескопа: Secure the Vixen-style dovetail plate (attached to the cradle rings) into the saddle of your compatible equatorial mount. Ensure all clamps are tightened to prevent movement.
- Attaching the Diagonal: Insert the 2-inch diagonal into the focuser drawtube. Secure it by tightening the thumbscrew(s) on the focuser.
- Inserting an Eyepiece: Insert your desired 2-inch eyepiece into the diagonal. If using a 1.25-inch eyepiece, you will need a 2-inch to 1.25-inch adapter (not included). Secure the eyepiece with the diagonal's thumbscrew(s).
- Attaching a Finder Scope (Optional): If you have a compatible finder scope, attach it to the pre-installed 2N1 finder scope base. Align the finder scope with the main telescope by pointing the main telescope at a distant terrestrial object and then adjusting the finder scope until the object is centered in both the finder and the main eyepiece.
- Extending the Dew Shield: Gently slide the integrated dew shield forward until it is fully extended.
6. Кіраванне тэлескопам
Пасля зборкі можна пачаць назіраць:
- Навядзенне тэлескопа: Use your mount's controls to point the telescope towards your desired celestial object. The finder scope, if installed and aligned, will help you quickly locate objects.
- Факусоўка: Look through the eyepiece and slowly turn the focuser knobs (coarse and fine adjustment) until the image appears sharp. Start with a low-power eyepiece (higher focal length) for easier focusing.
- Змена павелічэння: To change magnification, swap eyepieces. Lower focal length eyepieces provide higher magnification. Always refocus after changing eyepieces.
- Аб'екты адсочвання: As the Earth rotates, celestial objects will drift out of view. If using an equatorial mount, you can track objects by adjusting the right ascension axis, often with a motor drive (if equipped).
7. Тэхнічнае абслугоўванне
Proper care will ensure your telescope remains in excellent condition:
- Чыстка оптыкі: Dust on the objective lens is normal and rarely affects performance. If cleaning is necessary, use a soft brush or compressed air to remove loose particles. For stubborn smudges, use a specialized optical cleaning solution and lens tissue, applying minimal pressure. Avoid touching optical surfaces with bare hands.
- Ачыстка трубкі: Wipe the carbon fiber tube with a soft, damp тканіна. Пазбягайце абразіўных ачышчальнікаў.
- захоўванне: Store the telescope in a clean, dry, and dust-free environment. Keep the objective lens cap on when not in use.
- Focuser Maintenance: The 2.5-inch HEX focuser is designed for durability. If it becomes stiff or loose, consult the manufacturer's support for guidance; do not attempt to disassemble it yourself.
8. Выпраўленне непаладак
| праблема | Магчымая прычына | Рашэнне |
|---|---|---|
| Выява размытая або не ў фокусе. | Няправільнае становішча факусіроўшчыка; атмасферныя ўмовы. | Adjust the focuser slowly. Allow telescope to equalize with ambient temperature. |
| No image visible. | Lens caps on; incorrect eyepiece; object not in field of view. | Remove all lens caps. Ensure an eyepiece is inserted. Use the finder scope to locate the object. |
| Image appears dim. | High magnification eyepiece; light pollution. | Use a lower magnification eyepiece. Observe from a darker location. |
| Stars appear as streaks. | Mount not tracking; mount not polar aligned (for equatorial mounts). | Ensure tracking is engaged. Perform accurate polar alignment for astrophotography. |
