    I and many others here use Ted Molczan's ObsReduce in XY mode. It uses only
    (2 or) 3 star's pixel coordinates for reference, but is very accurate for
    small fields (even decent for my 28mm-equivalent wide angle).
    
    Of course you will have to estimate the center point of the beginning of
    each star track - also for the GEO if it is not perfectly stationary.
    
    Note that three stars are required, if your pixel readout is not
    right-handed orthogonal, which all my windows image processing software are
    (not) !
