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.
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.
