Askar AP 203/1421 OTA

203 mm: one of the largest apochromats you can buy

The Askar 203/1421 belongs to the absolute top class: one of the largest apochromatic refractors currently available. With a 203mm aperture and 1421mm focal length (f/7), this is an instrument for observatories and high-end astrophotography, where light gathering power and resolution meet at the refractor level.
