Introducing the most versatile inline auto focuser: the iOptron iAFSTM focuser with iLockTM technology! Utilizing a lead worm movement is the key to the iAFS focusers patented design; this method passively locks it at the exact position when movement is stopped, maintaining focus for most any sized payload even as the instrument angle is changed. The iAFS incorporates three movement control modes, USB (computer control), on board directional buttons (for powered manual adjustments) and a manual focus wheel to override the motorized adjustment. Other features include a built-in temperature sensor, dual USB-C ports, solid all metal body, fingerprint resistant surface, 0.6 micron resolution, and position limiters to prevent over runs. It comes standard with a 2 inch visual back, and optional telescope adapters to fit various OTAs are available. The iAFS focusers are available as the iAFS2 two inch model and the iAFS3 three inch version.
