Introducing the most versatile inline focuser available, the iOptron iAFS focuser with iLock technology. Utilizing a lead worm movement is the key to the iAFS focusers patented design; this passive position locking system secures most any payload (imaging train) at the stopped position, maintaining focus even as the instrument angle is changed. The iAFS incorporates three focus modes; USB (computer control), on board directional buttons (for powered manual adjustments) and a manual focus wheel to override the motorized adjustment. Other features of the iOptron iAFS2 include a built-in temperature sensor, multiple USB-C ports, solid all metal body, fingerprint-resistant exterior surface, 0.6 micron movement resolution, and position limiters to prevent over runs. The iAFS2, which is the 2" model, comes standard with a 2" visual back. Optional telescope adapters to fit various OTAs are available. Features of the iOptron iAFS2 Automatic Focuser...
