Askar 103APO – 103mm f/6.8 ED Triplet Apochromatic Refractor

The Askar 103APO is an apochromatic triplet refractor with an ED element, designed to offer high optical quality for both visual observation and astrophotography. With a 103 mm aperture and 700 mm focal length (f/6.8), it represents an ideal balance between portability and performance.

ED Triplet Optical Design

The three-element optical group includes ED (Extra-low Dispersion) glass to reduce chromatic aberration and improve image contrast. The apochromatic configuration allows for controlled color rendering and well-defined stars across the entire field.

f/6.8 Focal Ratio

The intermediate focal ratio ensures a good compromise between brightness and aberration control, making the instrument versatile for:

• Deep-sky astrophotography
• Planetary and lunar observation
• Imaging with APS-C and Full Frame sensors (with dedicated accessories)
• Use with optional reducers and flatteners

Mechanical Structure

The optical tube is designed to ensure stability and mechanical precision. The focuser system is sized to support astronomical cameras and advanced photographic setups.
