Askar 151PHQ APO 151/1057 f/7 is a professional astrograph dedicated to advanced astrophotographers as well as to enthusiasts of visual observations.
The heart of this telescope is a four-element, apochromatic optics with an air gap. In order to ensure the best possible correction of chromatic aberrations, Askar designers opted for a solution known from the most expensive, flagship apochromats, namely the use of two lenses made of glass with reduced dispersion (ED). In addition to excellent color reproduction, the Askar 151PHQ APO 151/1057 f/7 is characterized by maintaining a negligible field curvature, thanks to which even without the use of an additional flattener, the image on the edge of the frame is free from noticeable distortions.
The capabilities of this telescope are not limited to astrophotography alone. This instrument allows for visual observations by attaching a diagonal or eyepieces.
In addition to impeccable optical parameters, the Askar 151PHQ APO 151/1057 f/7 is distinguished by high quality and precision of mechanical elements. A solid extension allows for mounting even the heaviest astronomical cameras, and mounting rings and a Losmandy foot made in CNC technology guarantee full stability of the tube. • high-class astrograph with two low-dispersion lenses that eliminate chromatic aberrations
