Askar ACL200 Apo Telephoto Lens for Astrophotography and Landscape Photography

Askar is breaking new ground with the ACL200. For the first time, a full-fledged apochromatic refractor has been combined with the comfortable operation of a telephoto lens. Especially the requirements of astrophotographers have been taken into account. With the ACL200, perfect astrophotography can be achieved right from the start.
 

This is what distinguishes the ACL200 from conventional telephoto lenses:

♦ The optics is a 4-element APO with two ED special glasses for best possible color correction. The 2-element corrector is fixed in the tube and guarantees a distortion-free field up to full format.

♦ In addition to normal focusing for landscape photography, you still have microfocusing at the front end of the apo. A rotation of 360° causes a focus adjustment of only 1 mm! So you can focus to within 0.002 mm and then fix the optimal focus position.

♦ The apo has an M48x0.75 connection thread on the camera side with a working distance of 55 mm to the camera. This allows you to connect all common cameras (astro cameras, system cameras and of course DSLR) with the appropriate T-ring.

♦ The apo is equipped with a universal connection option with 360° rotation. This allows them to always position the object optimally in the camera. The connection plate (Arca-Swiss level) also offers a 3/8" and 1/4" female thread. With matching rails, you can also connect the Apo to the viewfinder shoe or to Vixen/EQ5-level quick couplers.

♦ Of course, you can also use the apo without restrictions for landscape and wildlife photography. The results will inspire.
