The ASKAR ACL200 & ZWO EAF bundle includes the ACL200 F/4 Apo lens, ZWO EAF electronic focuser, and mounting kit for attaching the EAF to the focus ring of the lens, enabling accurate software-controlled focusing during astrophotography.
The Askar ACL200 F/4 is a 4-element apochromatic refractor with a built-in 2-element corrector and two ED (extra-low dispersion) lenses, with the form factor of a traditional telephoto lens. Unlike traditional camera lenses, the ACL200 is designed specifically for the demands of astrophotography and is corrected across a full-frame image circle and has minimal chromatic aberration and distortion. Perfect for wide-field imaging on star trackers and compact enough to travel with.
Note: Unlike typical camera lenses, this is manual focus only.
