The Askar FMA135 F/4.5 is an extremely compact and lightweight triplet apochromatic refractor with one ED (extra-low dispersion) lens. The FMA135, when combined with the built-in three element flattener, is a very capable super wide-field astrograph with minimal chromatic aberration and distortion across an APS-C frame. As well as its superb imaging capability, it can be configured as a visual telescope, finder or guide scope.
