The Askar SQA130 f/4.8 130/624 is a professional Petzval-structure astrograph designed for use with full-frame and medium-format cameras. Its optical system consists of five elements, including two made from super low-dispersion (SD) glass, which ensures high contrast, excellent star sharpness, and effective chromatic aberration control. Thanks to the Petzval construction, the telescope is factory-flattened and does not require calculating the back-focus distance when used with the recommended connection length.
 
The SQA130 also features a refined mechanical design for smooth and precise operation in advanced astrophotography setups. The rear module provides thread adapters M48 / M54 / M68, offering wide compatibility with various imaging accessories. The astrograph supports both full-frame (44 mm) and medium-format (55 mm) sensors while maintaining strong illumination across the field.
 
The metal optical tube and retractable dew shield offer durability and convenience during transport and use. Optional accessories designed for the SQA series, such as the 20 mm extension tube and carrying handle, are fully compatible with the SQA130.
