          Gidday Parrish, Are the co-ords you have provided measured from the registered images? I think Mr Sungrazer will need them measured from the un-reg frames. The

            Gidday Parrish,
            Are the co-ords you have provided measured from the registered images?
            I think Mr Sungrazer will need them measured from the un-reg frames.

            The numbers are quite close to the co-ords I have posted. REG-ROI
            translates the images in X and in Y. So in these frames the object
            will be measured at differnet locations. Small x translations, but
            larger Y translations are happening with REG-ROI.

            Another check to do is to look at the very near by stars, as the
            object moves past particular stars, which are translated the same as
            the object, note its seperation.

            Can you also provide a pixel value of the brightest pixel you can
            find in the object. It should be in the results table after a point
            selection.

            I think its the same comet your are measuring here.

            Kind regards, Alan
