Askar V is a professional astrograph, which was the first in the world to be designed as an instrument with modular optics. This revolutionary design allows the telescope to be quickly adapted to current needs, whether it is to be used for astrophotography or visual observations.
The telescope tube connects to lenses with apertures of 60 and 80 mm, which, together with a dedicated flattener, reducer and extender, cover the focal length range from 270 to 600 mm. In terms of the optical system, the Askar V telescope is a three-element apochromatic refractor with an air gap, which thanks to two low dispersion lenses is characterized by excellent correction of chromatic aberration.
However, the possibilities of this telescope are not limited to astrophotography only. This instrument allows you to conduct visual observations after connecting the diagonal attachment or glasses with a diameter of 1.25" and 2". • professional astrograph with two low-dispersion lenses that eliminate chromatic aberrations
