Askar 185APO – 185mm f/7 ED Triplet Apochromatic Refractor

The Askar 185APO is a large-aperture apochromatic refractor designed to offer high performance in both visual observation and high-resolution astrophotography. With a 185 mm diameter and f/7 focal ratio, it combines brightness, contrast, and accurate color rendering.

ED Triplet Optical Design

The optical assembly consists of an apochromatic triplet with an ED element designed to reduce chromatic aberration and improve sharpness across the entire field. The color correction allows for high-contrast images of both planets and deep-sky objects.

Visual and Photographic Performance

• High-resolution planetary observation
• Deep-sky observation with high light-gathering capacity
• Photographic imaging with large-format sensors
• Detailed lunar imaging

f/7 Focal Ratio

The intermediate focal ratio provides a good balance between brightness and aberration control, making it versatile for both visual use and astrophotography with the potential use of a dedicated flattener or reducer.

Mechanical Construction

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