The Askar SQA130: A New Era in Astronomy Observations

On March 27, 2026, Sightron Japan will launch the Askar SQA130 telescope, a remarkable instrument renowned for its superior optical performance and stunning star images. With a large aperture of 130mm and a bright focal ratio of F4.8, this modern astrophotography telescope is designed to meet the needs of serious astronomy enthusiasts.

Unmatched Optical Performance

The SQA130 features a sophisticated air-spaced Petzval design utilizing a five-element group lens configuration. Out of these five elements, two are crafted from special low-dispersion SD glass, ensuring that optical aberrations are minimized to deliver extraordinarily sharp and high-contrast images throughout the entire field of view. This careful attention to optical design means that the telescope can produce flat images with minimal distortion, making it particularly valuable for astronomers seeking precision.

Exceptional Imaging Capabilities

Apart from its excellent optical design, the SQA130 boasts a generous image circle that supports medium format sensors (55mm in diameter), making it capable of covering large full-frame sensors (44mm in diameter) effectively. Users will appreciate the high peripheral illumination, with about 85% illumination at the edges for medium format and an impressive 95% for full-frame setups. The RMS spot radius in the center is an astounding under 2μm, while the edges deliver results under 2.4μm, significantly reducing the burden of image processing and producing incredibly precise star shapes.

Robust Yet Lightweight Mechanical Design

The telescope's body is crafted from aircraft-grade aluminum, which has undergone CNC machining for a lightweight yet robust construction. The hollow design ensures high rigidity while minimizing weight, making it easier to handle during use. Additionally, its large knob screws allow astronomers to easily open and adjust the telescope without needing tools, even when wearing gloves in cold weather. The design includes six mounting holes on the sides for attaching various accessories, ensuring flexibility during observation sessions.

Versatile and User-Friendly Features

The SQA130 is equipped with a high-precision rack-and-pinion focuser capable of smoothly and accurately adjusting focus, even with the weight of full-frame cooled CMOS cameras. An essential 360° rotating camera mount allows for accurate composition adjustments, with graduations for consistent angle settings. The dedicated top handle enhances portability and includes multifunction slots for finder bases. The design also accommodates dual finder base mounts for various attachments, streamlining the astrophotography setup process.

Comprehensive Accessories for Easy Usage

For added convenience, the SQA130 comes standard with three types of camera connection adapters, offering versatility for different equipment setups. Its retractable dew shield not only protects the optics from external light interference but also safeguards the front lens from moisture and physical impact, conveniently collapsing down to a compact length of just 650mm.

Furthermore, Sightron Japan includes a hard case made with Oxford fabric, featuring shock-absorbing foam padding for safe transportation of the telescope, making it ideal for field usage.
