Askar Apochromatischer Refraktor AP 55/264 SQA55 OTA

⭐ Quick Overview

Serious Optics At An Approachable Price

The Askar SQA55 uses a multi-element apochromatic lens design to control both chromatic aberration and field curvature — issues that can otherwise produce distorted stars toward the edges of an image. This makes it particularly well suited to modern astronomy cameras with large sensors, delivering sharp, round stars across the full frame.

Its light weight and compact size mean it can be carried comfortably on smaller tracking mounts, making it a practical choice both as a primary astrograph for beginners in imaging and as a lightweight travel companion for more experienced astrophotographers.

⭐ Great Value For The Optical Quality

Compared with many established apochromatic astrographs, the SQA55 offers a similar level of optical correction at a noticeably lower price point, making genuine multi-element apo imaging accessible to a wider range of astrophotographers.

🎯 Perfect For

📸 Built For Astrophotography

The SQA55 is sold as an optical tube assembly for use with a separate equatorial tracking mount and astronomy camera. It is designed around imaging performance rather than traditional eyepiece observing.

💡 Imaging Tips For Best Results

• Use a stable tracking mount matched to the combined weight of the tube and camera.
• Focus precisely using a Bahtinov mask or software autofocus routine.
• Allow the optics to reach ambient temperature before critical focusing sessions.
