The Askar SQA130 takes the acclaimed SQA series to a new level with a 130 mm aperture and fast f/4.8 focal ratio, delivering exceptional light-gathering power for demanding deep-sky astrophotography. Its quintuplet Petzval APO optical design with two SD glass elements produces superb optical correction and exceptionally sharp, round stars across a true flat field without the need for additional flatteners.
While all SQA models deliver flat fields ideal for full-frame sensors, the SQA130 extends this capability to support a 55 mm image circle that embraces medium-format cameras as well as full frame. This opens up more sensor real estate for ultra-high-resolution imaging and expansive deep-sky targets without corner distortion or complex spacing calculations.
The SQA130’s quintuplet Petzval APO design incorporates two premium SD (Super-Low Dispersion) glass elements that minimize chromatic aberration and maximize star point precision. With a native flat field and meticulous internal correction, stars remain tight and color-free from center to edge across wide-angle imaging setups.
Featuring a 624 mm focal length at f/4.8, the SQA130 provides an excellent balance of image scale and exposure efficiency for nebulae, galaxies, and star fields. The included M48/M54/M68 rear adapters and a recommended 55 mm backfocus range accommodate complex imaging trains with filters, guide cameras, and off-axis guiders. A robust dual-speed focuser, 360° rotator, and 300 mm Losmandy dovetail plate enhance usability for advanced workflows.
At approximately 9.18 kg for the OTA and around 11.76 kg fully equipped, the SQA130 requires a capable mount but remains transportable for field imaging sessions. A retractable dew shield and Oxford-cloth carrying case are included to protect optics and simplify setup and teardown.
Designed for serious astrophotographers who want both impressive aperture and the proven flat-field performance of the SQA line, the Askar SQA130 delivers professional-grade imaging capability across large sensors and demanding targets.
