Flattener 1.0x for Askar 140APO

The 1.0x flattener is specially designed to optimize the performance of the Askar 140APO telescope. Preserving a focal ratio of f/7 and a focal length of 980 mm, this flattener guarantees sharp, distortion-free images for high-quality observation and shooting. It effectively corrects field curvature and coma, enabling flatter field edges and sharper stars, for an optimized visual and photographic experience.

Key features

  • Optical design : This flattener adopts a triplet optical design, offering a 44 mm full-format image field, ideal for large sensors and ensuring image homogeneity across the entire surface.
  • Weight and dimensions :
    • Weight : 0.79 kg, a balance between sturdiness and manoeuvrability.
    • Diameter : 88 mm, guaranteeing perfect integration with Askar 140APO.
    • Total length : 111 mm, divided into several sections for optimized assembly.
  • Back Focus:
    • The rear focusing distance is standardized at 55 mm from the base of the M48 male thread, essential for precise optical adjustments, particularly for astrophotography configurations.
  • Compatibility and connections :
    • Front thread : M68×1, ensuring stable mounting on the telescope.
    • Rear thread : Several connection options, including M54×0.75 and M48×0.75, with a 2" filter thread (M48×0.75). These connection options allow great flexibility for various accessories, including cameras and filters.
  • Protection and finishing :
    • The flattener is CNC machined to a high-quality finish. It features threaded metal caps at both ends, protecting optical surfaces and threads when not in use, and keeping the flattener free from dust and scratches.

Additional accessories for Askar 140APO

In addition to the 1.0x flattener, the Askar 140APO is compatible with another premium accessory:

  • Reducer 0.8x : This reducer reduces the focal ratio to provide an enlarged field of view, ideal for observing large swathes of sky or capturing extended details in shots.
