Askar FRA Quintuplet Astrographs

Askar FRA astrographs are quintuplet apochromatic refractors with a flat, corrected field designed for imaging. The line includes the FRA300 Pro (60mm f/5), FRA400 and FRA400C (72mm f/5.6), FRA500 (90mm f/5.6) and FRA600 (108mm f/5.6), covering focal lengths from 300mm to 600mm.

Full-frame reducers bring the FRA400, FRA500 and FRA600 to f/3.9 for faster sessions on faint nebulae, a 0.7x full-frame reducer suits the FRA400C, and an AF kit motorizes its focus.
