Since their creation, the Askar astrographs of the FRA range (short focal ratio) have been very well received by astrophotographers around the world. The FRA400 model is a compact Petzval-type astrograph with a 72mm diameter and an f/5.6 aperture. Stars are sharp and fine, both at the center of the field of view and at the edges, even with a large sensor.
