- SKU ASK-SQA130
Pre-Order Now! First shipment estimated for late December, 2025!
The SQA130 is a 130mm quintuplet air-spaced SD Petzval astrograph with SD glass.
This amazing imaging scope has a focal length of 624 mm and a native focal ratio of f/4.8. The Askar SQA130 supports a 55mm image circle. It delivers exceptionally sharp stars, as demonstrated in published data charts.
Because the SQA130 has a self-flattening Petzval lens structure, users do not need to calculate specific back focus. Numerous mechanical details have been incorporated into the SQA130 to further enhance the user experience. Additionally, the optional SQA 20mm extension tube and handle are also compatible with the SQA130.



Rear-End Adapters: The end of the SQA130 includes an M68-M54-M48 step adapter for secure and easy connection to various imaging devices, such as full frame cameras.
Sliding Dew Shield: On the front end, the retractable dew shield can be moved into the forward position to protect the scope from dew and to keep contrast high by stopping external light sources from bouncing off the optics. When you are ready to pack up, simply unlock the thumb screw and slide the dew shield back to shorten the overall length of the OTA.
Multi-Platform Compatibility: Besides astronomy cameras, the SQA130 is also at home with mirrorless or DSLR cameras with the appropriate adapters.
