The V60 native focal ratio is f/6, and the focal length is 360mm. The V80 native focal ratio is f/6.25, and the focal length is 500mm. V is equipped with three additional accessories that are adjustable to 60mm or 80mm scales through rotation. The rear end of each accessory has M48 and M54 adapters with 2" built-in filter thread and the back focus is a standard 55mm. Using the reducer, can effectively reduce exposure time and expand the field of view to meet more of the shooting requirements. When the reducer is used with V60 objective lens, the focal length is reduced to 270mm, and the focal ratio is increased to f/4.5; when the reducer is used with V80 objective lens, the focal length is reduced to 384mm, and the focal ratio is increased to f/4.8.The V reducer unlocks the new performance of the Askar V, bringing more convenience and possibilities for your wide-field deep sky astrophotography. The V flattener improves field curvature, edge quality and reduces aberrations. When used with the 60mm objective lens, the focal length remains 360mm and the focal ratio is f/6, while when used with the 80mm objective lens, the focal length changes to 495mm and the focal ratio becomes f/6.18. The V flattener helps you make clearer and more professional photos. It is an indispensable aid to high quality photography. V extender, as the highlight of the product set, fully shows our none-stop innovation spirit and fulfill a part of the market vacant.
