Askar SQA Petzval Astrographs

Askar SQA astrographs are Petzval apochromatic refractors with five lens elements, designed for a flat field and fast imaging at f/4.8. Models include the SQA55, SQA70, SQA85, SQA106 and SQA130, plus the SQA60 Pro, a 60mm f/4.6 sextuplet.

The fast focal ratio and built-in field correction suit wide nebula fields with a dedicated astronomy camera. Accessories in this collection include SQA handle bars, with a quick-release version for the SQA55, and an autofocus kit for the SQA55.
