Askar 140APO – 140mm f/7 ED Apochromatic Triplet Refractor

The Askar 140APO is a high-quality apochromatic refractor designed to deliver high performance in both visual observation and astrophotography. With a 140 mm aperture and f/7.0 focal ratio, it represents an ideal balance between resolving power, brightness, and aberration control.

ED Triplet Optical Design

The optical system consists of an apochromatic triplet with an ED element, designed to reduce chromatic aberration and improve image contrast. The three-element configuration ensures high sharpness and controlled color rendering across the entire field.

Versatility of Use

• Detailed planetary observation
• High-resolution lunar imaging
• Deep-sky astrophotography
• Use with dedicated reducers and flatteners

f/7 Focal Ratio

The intermediate focal ratio offers a good compromise between brightness and aberration control, making the instrument suitable for both visual use and astronomical photography with large-format sensors.

Mechanical Structure

The optical tube is crafted with meticulous finishes and is designed to ensure mechanical stability. The focuser system is sized to support advanced photographic configurations.
