iOptron has introduced one of the most versatile inline focusers 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.
There are 2 models, the 2” iAFS20 and the 3” iAFS30, both are lead worm dive giving them almost unlimited holding power when stopped. They also can be computer controlled, manually focused with onboard buttons or by the wheel when no power is available.
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 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. The iOptron iAFS focuser with iLock technology comes standard with a two inch visual back, and optional telescope adapters to fit various OTAs are available. The iAFS focuser is available as the iAFS2 two inch model and the iAFS3 three inch version.
