Field levelers for 103APO

Flattener 1.0x for the Askar 103APO telescope

The 1.0x flattener is a premium accessory specifically designed to optimize the performance of the Askar 103APO telescope, maintaining a focal length of 700.4 mm and a focal ratio of f/6.8. It is ideal for astrophotography, correcting field curvature and coma, resulting in flatter field edges and finer stars, improving the overall quality of captured images.

Key features

• Design : This flattener adopts a triplet design, offering a supported image field of 44 mm, ideal for full-frame sensors. This configuration contributes to improved image sharpness and uniformity.
• Weight and dimensions :
• Weight : 0.58 kg
• Diameter : 88 mm
• Total length : 71.7 mm
• It is light enough not to unbalance the telescope, yet sturdy enough.
• Back Focus:
• Standardized 55 mm back focus distance, measured from the base of the M48 male thread. This precise back focus is essential for optimal optical settings, especially when using astrophotography cameras.
• Compatibility and connections :
• Front thread : M84×1
• Rear thread : M54×0.75 and M48×0.75, with 2" filter thread (M48×0.75 integrated).
• This flattener is equipped with two adapters (M54×0.75 and M48×0.75) for greater flexibility in connection with different cameras.
• Protection :
• Manufactured by CNC machining, it features threaded metal caps on both sides, protecting the threads and optical surfaces from dust and scratches when the flattener is not in use.

Additional accessories for Askar 103APO

The Askar 103APO offers three high-quality accessories, each providing specific options for different applications:

• Flattener 1.0x (shown here): optimizes performance for standard use with field correction.
• Reducer 0.8x reduces the focal ratio for a wider field of view.
• Reducer 0.6x The new "Lighter" function: offers even more pronounced reduction for capturing large scenes.

This 1.0x flattener is therefore a versatile and essential tool for astrophotographers wishing to exploit the full capabilities of their Askar 103APO telescope, guaranteeing a perfectly corrected image tailored to the demands of astronomical photography.
