The Askar 71F ('Flat Field') is a compact quadruplet astrograph with an aperture of 71 mm, a focal length of 490 mm and a native aperture ratio of f/6.9. The instrument features a quadruple apochromatic lens with air gap, including an ED element that effectively reduces chromatic aberration. The Askar 71F supports 44 mm full-frame imaging with excellent reproduction of stars at the edge of the field. An integrated flattener allows you to dispense with additional correctors.
