- No Back Focus Calculation: Simplifies setup as there's no need to calculate back focus distance within connection limits.
- Flatfield Optical Design: Eliminates the need for an additional 1x flattener, streamlining the imaging process.
- Премиум бүтүрүү: Ivory and pimply coating on the main tube for improved grip and aesthetic appeal.
3. Components Overview
Familiarize yourself with the main components of your Askar 80PHQ Telescope:
- Optical Tube Assembly: The main body housing the lenses.
- Фокустоочу: Mechanism for adjusting focus, typically with fine and coarse adjustments.
- Tube Rings: Securely hold the optical tube to the mounting plate.
- Каптал табак: Attaches the telescope to a mount.
- туткасы: For easy carrying and mounting.
- Dew Shield: Extends from the front of the telescope to prevent dew formation on the objective lens and block stray light.

4. Орнотуу жана чогултуу
Follow these steps to assemble your Askar 80PHQ Telescope:
- Пакеттен чыгаруу: Бардык компоненттерди таңгактан кылдаттык менен алып салыңыз. Кандайдыр бир зыянды текшериңиз.
- Телескопту орнотуу:
- Attach the dovetail plate to your astronomical mount. Ensure it is securely fastened.
- Place the optical tube, secured by its tube rings, onto the dovetail plate. Tighten the clamps on the tube rings to hold the telescope firmly.

- Аксессуарларды тиркөө:
- Eyepieces (for visual observation): Insert your desired eyepiece into the focuser. Secure it with the thumbscrew.
- Camera (for astrophotography): Connect your camera to the focuser using appropriate adapters. The 80PHQ's design simplifies this by not requiring complex back focus calculations.
- Finderscope: Attach the finderscope to its designated bracket on the telescope tube.

- Dew Shield Extension: Extend the dew shield fully before observation or imaging to protect the objective lens.
5. Телескопуңузду иштетүү
5.1. Visual Observation
- Максаты: Use the finderscope to locate your desired celestial object. Center the object in the finderscope's crosshairs.
- Фокустоо: Look through the eyepiece and slowly adjust the focuser knobs until the image is sharp and clear. Start with coarse adjustment, then fine-tune.
- Окуляр тандоо: Experiment with different eyepieces to achieve varying magnifications. Lower magnification eyepieces (longer focal length) provide a wider field of view, while higher magnification eyepieces (shorter focal length) offer more detail.
5.2. Astrophotography
The Askar 80PHQ is optimized for astrophotography due to its flatfield optical design and integrated lens system.
- Камеранын туташуусу: Ensure your camera is securely attached to the focuser using the appropriate adapters.
- Полярдык тегиздөө: For long-exposure astrophotography, accurate polar alignment of your equatorial mount is crucial. Refer to your mount's manual for detailed instructions.
- Focusing for Imaging: Achieve precise focus using a Bahtinov mask or software-assisted focusing tools. The focuser's fine adjustment allows for critical focus.
- Жетектөөчү: For exposures longer than a few seconds, an autoguider system is recommended to compensate for tracking errors and ensure sharp stars.
- Image Acquisition: Use your camera's software or dedicated astrophotography software to control exposures, ISO, and other settings.
Маанилүү эскертүү: The Askar 80PHQ's integrated lens combination means you do not need to add an external 1x flattener, simplifying your imaging train and setup.
6. Техникалык тейлөө жана кам көрүү
- Линзаны тазалоо: Only clean the objective lens when absolutely necessary. Use a soft brush to remove dust, then a specialized optical cleaning solution and microfiber cloth. Avoid touching the lens surface with bare hands.
- Түтүк тазалоо: Wipe the telescope tube with a soft, damp кездеме. Абразивдүү тазалагычтардан алыс болуңуз.
- Сактагыч: Store the telescope in a dry, dust-free environment, preferably in its original case or a padded bag. Ensure the dew shield is retracted and lens caps are on.
- Температурага көнүү: Allow the telescope to acclimate to the ambient outdoor temperature for at least 30-60 minutes before use to minimize thermal currents within the tube.
7. Кыйынчылыктарды
| Көйгөй | Мүмкүн себеп | Чечим |
|---|---|---|
| Fuzzy or blurry images | Out of focus; poor seeing conditions; thermal currents. | Adjust focuser carefully; wait for stable atmospheric conditions; allow telescope to acclimate. |
| Stars appear elongated (astrophotography) | Poor polar alignment; tracking errors; no guiding. | Re-do polar alignment; use autoguider; check mount tracking. |
| Dew on objective lens | High humidity; insufficient dew shield extension. | Ensure dew shield is fully extended; use a dew heater strip. |
| No image visible | Lens caps on; wrong eyepiece/camera connection; object not in field of view. | Remove all lens caps; check connections; re-aim telescope using finderscope. |
