Unveil the Cosmos with Precision: Askar 103mm Apochromatic Telescope

Embark on a celestial journey like never before with the Askar 103mm Apochromatic Telescope. Crafted with precision and equipped with advanced features, this telescope is your gateway to capturing stunning images and experiencing the wonders of the night sky.

Key Features:

  1. Triplet APO Design: The Askar 103mm boasts a triplet air-spaced APO lens design, including ED glass. This advanced design corrects chromatic aberration, providing exceptional image quality with true color accuracy.
  2. Aperture Advantage: With a 103mm aperture, this telescope offers superior light-gathering power, resolution, brightness, and contrast. Capture more light and reveal intricate details of celestial objects in your images.
  3. Enhanced Optical Elements: The telescope incorporates ED glass (Extra-low Dispersion), specifically designed to reduce chromatic aberration. This results in sharper images with minimal color fringing.
  4. Dew Shield and Inner Coating: The inner surface of the dew shield is covered with matting felt, while the inner walls of the main tube are coated with matting paint and equipped with an internal baffle. These features reduce light scattering and reflection inside the OTA, enhancing brightness, contrast, and resolution.
  5. Finder Bases and Multi-Functional Handle: Equipped with two finder bases and a specially designed handle with a slot for installing a finder scope, the Askar 103mm ensures flexibility and convenience for users. The lightweight tube rings with raised bases create additional space for mounting astronomical accessories.
  6. Optional Accessories: Choose from three advanced accessories – 1x flattener, 0.8x reducer, and 0.6x focal reducer. These accessories, equipped with 2" filter threads and M54/M48 adapters, enhance your telescope's versatility and performance.
  7. Detachable Tube Design: The telescope's detachable tube design allows for a focal ratio adjustment from the native F6.8 to F4, making it suitable for observations with a binoviewer.
  8. High-Precision Focuser: The dual-speed rack and pinion large 3.3-inch rigid focuser ensures smooth and precise focusing. The anti-reflective internal design and matting paint eliminate stray light for optimal image quality.
  9. 360° Rotator: The 360° high-precision big rotator at the rear of the focuser, with precise scales and an enlarged locking screw, enables convenient adjustment and secure rotation even under high loads.
