4. Idantifikasyon konpozan

Familiarize yourself with the main parts of your telescope:

• Lantiy objektif: 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.
• Dyagonal: An optical accessory that redirects the light path at a 90-degree angle, providing a more comfortable viewpozisyon ing.

5. Enstalasyon

Follow these steps to set up your telescope for observation:

1. Monte teleskòp la: 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.
2. Attaching the Diagonal: Insert the 2-inch diagonal into the focuser drawtube. Secure it by tightening the thumbscrew(s) on the focuser.
3. 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).
4. 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.
5. Extending the Dew Shield: Gently slide the integrated dew shield forward until it is fully extended.

6. Fonksyone Teleskòp la

Once assembled, you can begin observing:

1. Montre teleskòp la: 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.
2. Konsantre: 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.
3. Chanje Agrandisman: To change magnification, swap eyepieces. Lower focal length eyepieces provide higher magnification. Always refocus after changing eyepieces.
4. Tracking Objects: 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. Antretyen

Proper care will ensure your telescope remains in excellent condition:

• Netwayaj Optik: 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.
• Cleaning the Tube: Wipe the carbon fiber tube with a soft, damp twal. Evite pwodui netwayaj abrazif.
• Depo: 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.
