Askar ACL200 is an optical device especially for optimizing the quality of astrophotography, while it also caters to the needs of ground imaging. It’s compact, lightweight and easy to operate, an ideal combination of astrograph and camera lens. The optical outcome is to be dramatically improved as the distortion around the edge and achromatic aberration are greatly controlled. Askar ACL200 will bring you sharp and excellent celestial images together with a better experience of exploration.

The world-first 200mm professional astrophotographic lens is designed with a similar appearance as an ordinary camera lens which features an integrated structure. It’s compact, light and easy to use.

Askar ACL200 is precisely designed to optimize the quality of sky imaging. This ingenious optical apparatus successfully gets rid of otherwise redundant optical accessories. You have no problem in operating ACL200 if you are familiar with ordinary cameras.

Dual focal adjustment for astrophotography. Coarse and fine (1mm) adjustment make your focal adjustment more quick and convenient.

Built-in f/4 to f/22 adjustable aperture size enables Askar ACL200 an ingenuity also for ground imaging. Its focus distance is of 3 meters.

You will no longer worry about the vagueness of the images stemming from vignette or achromatic aberration. Askar ACL200 full frame astrophotographic lens with built-in flattener can help you solve comatic or other aberrations. Relatively fast f/4 focal ratio can effectively shorten exposure time and reduce the astrophotographic burden of the equatorial mount due to long-time tracking.

We did some modification on the old ACL200, hoping to improve our customers’ experience with it, which includes a handle with standard Vixen dovetail finder slot, a new-type mounting ring and two extra thumbscrews.

Compared with the old mounting ring, the new ring has an extruding stalk for the installation of the handle. And the new-added handle with Vixen-style dovetail finder slot is for many purposes of attachment like finders or ASI air controllers. Further more, the handle can also go with a dual-connection of a controller and a finder as the length of which accommodates both accessories.

This lens is designed with triplet of six lenses, among which two pieces of ED ultra-low dispersion glass are added, making it better than ordinary lens in reducing chromatic aberration and have clearer image.
