Askar 60F Flat-Field - Ultra Portable Quadruplet APO Scope for Full Frame Astrophotography<\/h2>\n

L'Askar 60F Flat-Field<\/strong> is a compact apochromatic refractor designed for demanding astrophotographers looking for an ultra-portable, high-performance, easy-to-use instrument. With its 60 mm aperture, 408 mm focal length and native focal ratio of f\/6.8<\/strong>, This scope offers an excellent balance between wide field of view, optical quality and ease of transport.<\/p>\n

Thanks to its design APO quadruplet with spaced lenses<\/strong>, With its ED glass element, the Askar 60F delivers fine, high-contrast stars while effectively reducing chromatic aberrations. Its built-in field corrector allows immediate use without complex backfocus calculations or the addition of an external flattener.<\/p>\n

An astrographic telescope designed for modern astrophotography<\/h3>\n

The Askar 60F has been developed to simplify the astrophotography experience as much as possible. Unlike many scopes that require additional accessories, this version directly integrates a field corrector optimized for sensors up to full format 24\u00d736 mm<\/strong>.<\/p>\n

The image circle of 44 mm<\/strong> ensures excellent coverage of Full Frame sensors, with clean stars right down to the corners. Simply connect your camera, focus and begin acquisition.<\/p>\n

The tube comes with several compatible photo adapters M48x0.75<\/strong> and M54x0.75<\/strong>, This makes it easy to integrate with the majority of astronomical and SLR cameras on the market.<\/p>\n

High-quality APO quadruplet optics<\/h3>\n

The optical system is based on a formula quadruplet air-spaced APO<\/strong> comprising three front lenses and a rear corrective lens. The presence of an ED glass element greatly reduces chromatic aberration, resulting in high-contrast, detailed images.<\/p>\n

This design makes the Askar 60F particularly suitable for :<\/p>\n

    \n
  • Wide-field astrophotography<\/li>\n
  • Extended nebulae<\/li>\n
  • Open clusters<\/li>\n
  • The great fields of the Milky Way<\/li>\n
  • Advanced night landscapes<\/li>\n<\/ul>\n

    Ultra-compact and easy to transport<\/h3>\n

    With only 2.36 kg<\/strong> on the scale and reduced length thanks to its retractable mist guard, the Askar 60F is ideal for nomadic astronomers and travelers.<\/p>\n

    The optical tube measures only :<\/p>\n

      \n
    • 289 mm with fog shield retracted<\/li>\n
    • 323 mm with extended fog shield<\/li>\n<\/ul>\n

      Even equipped with its photo accessories, the scope remains extremely compact, making it a perfect candidate for lightweight frames and travel setups.<\/p>\n

      High-precision 2.4\u201d Rack & Pinion eyepiece holder<\/h3>\n

      Askar 60F is equipped with a sturdy eyepiece holder 2.4\" Rack & Pinion<\/strong> offering excellent mechanical rigidity even with heavy cameras.<\/p>\n

      They include :<\/p>\n

        \n
      • Fine 1:10 gear ratio<\/li>\n
      • 360\u00b0 graduated rotation<\/li>\n
      • Excellent mechanical stability<\/li>\n
      • 50 mm focus stroke<\/li>\n<\/ul>\n

        The rotation system facilitates precise framing for astrophotography, while the gear ratio allows extremely fine focusing.<\/p>\n

        Premium mechanical design<\/h3>\n

        The Askar 60F benefits from particularly careful CNC manufacturing, with an elegant blue and white finish. The inside of the tube is lined with an absorbent material that limits stray reflections and enhances contrast.<\/p>\n

        The top handle incorporates a finder holder and two additional bases are provided on each side of the focuser for easy mounting:<\/p>\n

          \n
        • A researcher<\/li>\n
        • A guide<\/li>\n
        • A stellavite<\/li>\n
        • Complementary accessories<\/li>\n<\/ul>\n

          The 230 mm Vixen dovetail also includes 1\/4\u201d and 3\/8\u201d threads, enabling direct attachment to photo tripods.<\/p>\n

          Compatible with visual observation and astrophotography<\/h3>\n

          Although optimized for imaging, the Askar 60F can also be used for visual observation thanks to its 1.25\u201d and 2\u201d adapters.<\/p>\n

          This makes it an excellent small, wide-field scope for :<\/p>\n

            \n
          • Star clusters<\/li>\n
          • Ground observations<\/li>\n
          • The Moon<\/li>\n
          • Nomadic observations<\/li>\n<\/ul>\n
