Askar 3" 0.7x Full-Frame gearbox - Specifications and features

Visit Askar reducer 3 inches 0.7x is specially designed for 107PHQ and 130PHQ astrographs. This model uses a triplet design with ED glass to minimize chromatic aberrations and improve optical quality. This reducer is compatible with full-frame sensors, offering full image coverage without vignetting. Its 0.7x reduction shortens the focal ratio and maximizes the field of view, ideal for astrophotographers seeking to capture extended celestial objects.

Askar 3" 0.7x Reducer specifications

  • Reduced focal ratio : 4.9 for the 107PHQ, optimizing brightness and enabling shorter exposure times.
  • Reduced focal length : 524 mm for the 107PHQ, ideal for observing large celestial objects and for faster, more precise astrophotography.
  • Lens design : Triplet with ED glass for reduced aberrations and enhanced sharpness right to the edge of the field.
  • Rear focal length : 55 mm, standard for compatibility with many astrophotography accessories.
  • Full-frame compatibility : Ensures vignette-free images, even with large sensors, for uniform, detailed capture.

Dimensions and Additional Specifications

  • Outside diameter : 80 mm, ensuring robust construction for stable configurations.
  • Total length : Adjusted for compact mounting and easy handling in astrophotography setups.
  • Front thread : M77*1, for easy integration with PHQ series optical equipment.
  • Thread adapters : Includes M681, M540.75, and M480.75, for maximum flexibility and extended mounting possibilities. The M480.75 thread also allows installation of 2" filters.

Benefits for users

This reducer is designed to increase the field of view and reduce exposure time, optimizing the efficiency of deep-sky astrophotography sessions. By increasing the field of view and lowering the focal ratio, it offers astrophotographers greater flexibility and convenience in capturing precise, detailed images of large celestial objects. Its compatibility with full-frame sensors maximizes image coverage, eliminating loss of edge-of-field detail.
