iOptron iAFS2 2" Focuser
Description
iOptron’s iAFS2 is an inline automatic focuser engineered for rock-solid focus retention. A patented lead screw locks focus as soon as motion stops, eliminating shift under changing angles or payloads. Control is available via USB with ASCOM and INDI drivers, onboard directional buttons, or a manual knob that works unpowered. The all-metal housing resists fingerprints, mechanical limiters protect travel, and a 2" visual back is supplied. Telescope adapters are sold separately.
