Informacje dotyczące bezpieczeństwa

• Never look directly at the sun through your telescope or its finderscope without a professionally manufactured solar filter. Może to spowodować trwałe i nieodwracalne uszkodzenie oczu.
• Nie pozostawiaj teleskopu bez nadzoru, zwłaszcza w obecności dzieci.
• Aby uniknąć zarysowań lub uszkodzeń, należy obchodzić się z elementami optycznymi ostrożnie.
• Ensure the telescope is placed on a stable, level surface to prevent tipping.
• Keep all accessories and small parts out of reach of small children.

Konfiguracja i montaż

The Sky-Watcher Flextube Dobsonian is designed for quick and easy setup. The optical tube and base separate for convenient transport and storage.

1. Assembling the Mount Base

Follow the included assembly instructions for the Dobsonian mount base. Ensure all screws are tightened securely for stability. The base provides smooth azimuth (horizontal) movement.

2. Podłączanie tuby optycznej

Carefully place the optical tube assembly onto the mount base. Secure it using the provided tension control handles. These patented handles allow for precise slewing and aiming, ensuring smooth altitude (vertical) movement.

3. Extending the Flextube

The Flextube design uses three retractable steel struts. Gently extend the upper section of the optical tube until the struts lock into their preset indentations. This design maintains collimation and provides a rigid optical path.

4. Installing the Focuser and Eyepieces

Insert the 2-inch Crayford-style focuser into the optical tube. If using 1.25-inch eyepieces, insert the 1.25-inch adapter into the focuser. Then, insert your desired eyepiece (e.g., 25mm or 10mm Plossl) into the focuser/adapter and secure it with the thumbscrew.

5. Attaching the Finderscope

Mount the 8x50 RACI finderscope onto its bracket on the optical tube. Align the finderscope with the main telescope during daylight hours by pointing the main telescope at a distant, stationary object (e.g., a telephone pole) and then adjusting the finderscope's alignment screws until the object is centered in both the finderscope and the main telescope's eyepiece.

6. Using the Eyepiece Tray

The convenient eyepiece tray attaches to the mount base, providing a secure place to store your eyepieces and other small accessories during observation.

Observing Basics

• Choosing an Eyepiece: Start with the 25mm eyepiece for a wider field of view and easier object location. Once an object is centered, switch to the 10mm eyepiece for higher magnification.
• Skupienie: Use the focuser knobs to achieve a sharp image. Turn the knobs slowly and carefully until the image is clear. The Crayford-style focuser provides smooth and precise focusing.
• Lokalizacja obiektów: Use the 8x50 finderscope to locate celestial objects. Once an object is visible in the finderscope, it should be within the field of view of your main telescope's low-power eyepiece.
• Śledzenie: Dobsonian telescopes require manual tracking. Gently nudge the telescope to follow the movement of celestial objects across the sky due to Earth's rotation. The Teflon bearings ensure smooth azimuth movement.

Optical Care

The mirrors of your Sky-Watcher telescope are constructed with borosilicate glass and coated with quartz, titanium, and silicon dioxide for 94%+ reflectivity. Proper care ensures their longevity and performance.

• Czyszczenie luster: Avoid frequent cleaning of the primary and secondary mirrors. Dust can be gently removed with a soft camel hair brush or a can of compressed air (use short bursts, hold upright). For stubborn smudges, consult a specialized telescope cleaning kit or professional.
• Eyepiece Cleaning: Eyepieces can be cleaned with a lens cleaning solution and a microfiber cloth designed for optics.
• Składowanie: When not in use, store the telescope in a dry, dust-free environment. Use the provided dust caps for the optical tube and focuser. The collapsible design allows for easier storage.

Kolimacja

Collimation is the alignment of the telescope's mirrors. While the Flextube design holds collimation well, occasional checks and adjustments may be necessary for optimal performance, especially after transport. Refer to online resources or specialized guides for detailed collimation procedures using a laser collimator or Cheshire eyepiece.
