We show the astrometric potential of the Wide Field Imager at the focus of
the MPI-ESO 2.2m Telescope. Currently, we are able to measure the position of a
well-exposed star with a precision of ∼4 mas/frame in each coordinate
(under 0.8 arcsec seeing conditions). We present some preliminary results here.Comment: 4 pages, 3 figures, from "Astrometry in the Age of the Next
