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.2" Visual Back IncludedTelescope Adapter NOT included Features High precision stepper motor with position over-run protection Built-in temperature sensor Built-in CAA Quiet, smooth, fast operation Compact and lightweight Zero backlash Dual USB-C port for computer connection and firmware upgrade ASCOM and INDI compatible Low power consumption with USB2.0 (type-C) powering Manual adjustment (powered or unpowered) Position memorizing during power off Compatible with most OTAs with proper adapter Package includes: 1X iAFS3 3" focuser 1X 2" Visual Back (P-FA30-VB) 2X USB2.0 (Type-C) cable Focuser Inline Auto Focuser with iLock™ Focuser Size 3" Dimensions 94 X 133 X 108mm Weight 1062g Clear Aperture 68mm Maximum payload 6kg Drawtube Travel Distance 30mm Focusing Resolution 0.4um Power/Communication Port Type-C USB2.0 port X2 Driving train Stepper motor Computer Control Yes (ASCOM and INDI) Automatic Focusing Yes Motorized Focusing Button Yes Manual Focusing Yes (with override) Temperature Sensor Yes (Built-in) Camera Angle Adjustment Yes Warranty One year limited
