This beautifully compact 200 mm f/4 lens, with its apochromatic sextuplet optical design and built-in flattener, is a great solution for astronomers who want a quality lightweight imaging set up for either a DSLR or astronomy imaging camera. It's six optical elements are in three groups and include two ED (extra low dispersion) elements to control chromatic aberration while producing sharp, high contrast images.

The Askar ACL200 is the first manual focus camera lens designed with astronomical imaging in mind, but it works perfectly well for terrestrial photography, too. You can stop down your aperture to a minimum of f/22 for work in daylight. Focus is achieved by either turning the course focus ring or by using the 1 mm micro focusing ring. A 360-degree rotatable collar allows you to frame the image to your liking.

The new Askar ACL200 f/4 Astronomy Camera Lens has all the optical quality of the original version but comes with a totally redesigned rear mounting ring that includes a convenient handle with a standard Vixen dovetail on the top.  The red dovetailed handle can easily accept accessories like the popular ASIAIR Pro or the Askar finder.  In fact, it can hold both at the same time!  For more info on the updated Askar ACL200 mounting ring, you can watch the video below, or check out the photo which shows different ways to mount a finder or ASIAIR.

 

 

It is easy to add a filter to the ACL200. It accepts 82mm filters on the front, just like a regular camera lens, but you can also thread a 2" filter to the rear filter adapter.
