Description:
- 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 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 two inch visual back, and optional telescope adapters to fit various OTAs are available. 

Features:
- Compatibility: for ASCOM, INDI, AstroBox
- Integration: Drive motor at the same direction as the focusing tube moving to reduce Z-axis imbalance.
- Three Ways to Focus:
  All Time Manual Focusing
  Power Button focusing: press and hold for fast tuning, short press for fine tuning
  Dual Type-C USB2.0 Ports: USB powered mount control, flexible connection
- Internal Position Limiters: built-in position limiters will stop focuser overrun to protect the motor and focuser. Two sets of 2xM4 threaded holes for attaching guiding scope and Astrobox.
- Built-in Temperature Sensor: for temperature compensation during auto-focusing.
- Built-in CAA: high precision CAA for easy image alignment and composition.
- Adjustable Camera Ring: set screws on camera ring for angle fine adjustment between a filter wheel and focuser.
