The groundbreaking Askar ACL200 lens is the first camera lens specifically designed for astronomical imaging. This 200mm f/4 apochromatic lens incorporates six elements in three groups including two ED elements to minimize chromatic aberration. For astronomical applications, the Askar ACL200 outperforms traditional telephoto and zoom lenses costing far more.

With a focal ratio as fast as f/4, the manual focus Askar ACL200 lens is ideal for deep-sky wide-field astrophotography with full-frame DSLR, mirrorless, and dedicated astronomy cameras using an optional 48mm T-ring adapter. The working distance is 55mm. It can also be used with cropped-sensor cameras for which it will provide a longer effective focal length. The lens includes a manual aperture ring and precision coarse and fine manual focusing mechanisms with a distance scale that make it easy to snap stars into a tight focus. It also incorporates a filter adapter to enable the use of standard 2" astronomical filters.

For the price, this fast apochromatic lens offers excellent value and can approach the performance of telescopes that cost three or four times as much. This is especially true when matched with astronomy cameras with smaller 1" and 4/3" sensors. Cameras with larger APS-C and full-frame sensors may reveal slight aberrations at the edge of the field.

This lens is equipped with collar that allows 360° rotation for optimal framing of celestial objects. The Arca-Swiss style connection plate offers a 3/8" and 1/4" female threads for mounting to a tripod, and the plate also fits standard Vixen-style saddles. The lens weighs just 1.5kg so it's ideal for use on lightweight star tracker mounts.

With an adjustable focal ratio from f/4 to f/22, it also makes a great camera lens for wildlife, landscapes, and portraiture. The minimum focusing distance is approximately 3 meters.
