A WORLD FIRST! Structure and appearance of a camera lens, but with a performance of a high quality APO telescope!

The ASKAR ACL200has been specifically designed for astrophotography, whilst it meats the requirements of landscape photography. A unique focusing solution, coarse and fine focusing rings with locking knobs provide the ultimate astro photo experience. 

A groundbraking product for full frame cameras that perfectly combines the usual features of a telescope and a telephoto camera lens.

When using it for deep-sky imaging, it will produce clear and sharp images with minimal amount of distortion and chromatic aberration, resulting in great astrophotos of highest quality. The built-in filter holder that accepts a 2" filter will help to achieve your goal: use a light pollution filter (like the Optolong L-Pro) or/and a H-alpha filter and combine them into a single image. Instead of a H-alpha filter you could also consider a dual or triple narrowband filter, like the ZWO 2" DB filter or Optolong 2" L-eNhance or 2" L-eXtreme.

Although not exactly lightweight, you can be assured that it is built to last and will serve you many years if handled with care.
