Kullanım Talimatları

  1. Finder Kapsamını Hizalama:

    Before observing, align the finder scope with the main telescope. Point the main telescope at a distant, easily identifiable object (e.g., a tree top or a street light during the day). Look through the finder scope and adjust its alignment screws until the object is centered in its crosshairs. Then, check through the main eyepiece to ensure the object is also centered there.

  2. Observing an Object:

    Once the finder scope is aligned, use it to locate your desired celestial object. Center the object in the finder scope's crosshairs. Then, look through the main telescope's eyepiece. You may need to make minor adjustments to the telescope's position using the AZ mount's handles.

  3. Odaklanma:

    Turn the focuser knob (located near the eyepiece) slowly until the image appears sharp and clear. The focuser has a scale for precise adjustment.

  4. Büyütme Oranını Değiştirme:

    To change magnification, swap eyepieces. The 20mm MA eyepiece provides 25X magnification (500mm focal length / 20mm eyepiece focal length). The 4mm aspheric eyepiece provides 125X magnification (500mm / 4mm). For even higher magnification, insert the 2X Barlow lens into the focuser first, then insert an eyepiece into the Barlow lens. This doubles the magnification of any eyepiece used with it.

  5. Akıllı Telefon Adaptörünü Kullanma:

    If included, attach the smartphone adapter to an eyepiece. Secure your smartphone to the adapter and align its camera with the eyepiece to capture images or videos through the telescope.

Bakım

  • Lens Temizliği: Use a soft, lint-free cloth specifically designed for optical lenses. For stubborn smudges, use a small amount of optical cleaning fluid. Avoid touching the lens surfaces with your fingers.
  • Depolamak: When not in use, store the telescope in its carrying bag in a dry, dust-free environment. Keep dust caps on the objective lens and eyepieces.
  • Genel Bakım: Avoid exposing the telescope to extreme temperatures or humidity. Do not disassemble the optical components unless instructed by a qualified technician.

Sorun giderme

  • Görüntü bulanık: Adjust the focuser knob slowly until the image is sharp. Ensure the eyepiece is fully inserted and secured.
  • Nesneler bulunamadı: Ensure the finder scope is properly aligned with the main telescope. Start with the lowest magnification eyepiece (20mm MA) to get a wider field of view.
  • Image is dim: This is normal for very high magnifications or when observing faint objects. Ensure your objective lens is clean. Observe from a dark location away from light pollution.
  • Telescope is unstable: Ensure the tripod legs are fully extended and locked, and the accessory tray is attached for added stability. Place the tripod on a flat, firm surface.

Kullanıcı İpuçları

  • Start with Low Magnification: Always begin observing with the lowest magnification eyepiece (20mm MA) to easily locate and center objects. Once centered, you can switch to higher magnification eyepieces.
  • Observe from Dark Locations: For the best astronomical views, find a location away from city lights and light pollution.
  • Allow for Temperature Acclimation: If moving your telescope from a warm indoor environment to a cold outdoor one, allow it some time (15-30 minutes) to accustom to the ambient temperature. This helps prevent image distortion due to temperature differences.
  • Practice Terrestrial ViewTürkçe: Before attempting complex astronomical observations, practice using your telescope for terrestrial viewing during the day. This helps you get familiar with focusing and tracking.
