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 focuser's 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 amanual focus wheel to override the motorized adjustment. Other features include a built-in temperature sensor, multiple USB-C ports, solid all metal body, fingerprint resistant exterior surface, 0.6 micron movement resolution, position limiters to prevent over runs. It comes standard with a 2-inch visual back and optional telescope adapters to fit various OTAs.
