We propose and demonstrate a low-cost magnetomechanical fiber micro-positioner for optical coupling, with a square-millimeter working range and a resolution of a few microns per pixel. We demonstrate the functionality of the positioner as a beam pattern imaging system for a 14” Dobsonian telescope as it is compact enough to be mounted instead of a small-telescopes eye-piece. The aim is to use this positioner to couple and stabilize a telescope beam to a single-mode fiber. We make a first approach to a reference model controller showing an increase of the average coupled power under perturbations from 54% to 85%.
